Poiesis
In philosophy and semiotics, ''poiesis'' (from grc, ποίησις) is "the activity in which a person brings something into being that did not exist before." ''Poiesis'' is etymologically derived from the ancient Greek term ποιεῖν, which means "to make". It is related to the word ''poetry'', which shares the same root. The word is also used as a suffix, as in the biological term hematopoiesis, the formation of blood cells. Overview In the ''Symposium'', a Socratic dialogue written by Plato, Diotima describes how mortals strive for immortality in relation to poiesis. In all begetting and bringing forth upon the beautiful, there is a kind of making/creating or poiesis. In this genesis, there is a movement beyond the temporal cycle of birth and decay. "Such a movement can occur in three kinds of poiesis: (1) Natural poiesis through sexual procreation, (2) poiesis in the city through the attainment of heroic fame, and, finally, (3) poiesis in the soul through the cultiva ...

Autopoiesis
The term autopoiesis () refers to a system capable of producing and maintaining itself by creating its own parts. The term was introduced in the 1972 publication '' Autopoiesis and Cognition: The Realization of the Living'' by Chilean biologists Humberto Maturana and Francisco Varela to define the self-maintaining chemistry of living cells. Since then the concept has been also applied to the fields of cognition, systems theory, architecture and sociology. Overview In their 1972 book ''Autopoiesis and Cognition'', Chilean biologists Maturana and Varela described how they invented the word autopoiesis. They explained that, They described the "space defined by an autopoietic system" as "self-contained", a space that "cannot be described by using dimensions that define another space. When we refer to our interactions with a concrete autopoietic system, however, we project this system on the space of our manipulations and make a description of this projection."

Hematopoiesis
Haematopoiesis (, from Greek , 'blood' and 'to make'; also hematopoiesis in American English; sometimes also h(a)emopoiesis) is the formation of blood cellular components. All cellular blood components are derived from haematopoietic stem cells. In a healthy adult person, approximately – new blood cells are produced daily in order to maintain steady state levels in the peripheral circulation.Semester 4 medical lectures at Uppsala University 2008 by Leif Jansson Process Haematopoietic stem cells (HSCs) Haematopoietic stem cells (HSCs) reside in the medulla of the bone (bone marrow) and have the unique ability to give rise to all of the different mature blood cell types and tissues. HSCs are self-renewing cells: when they differentiate, at least some of their daughter cells remain as HSCs so the pool of stem cells is not depleted. This phenomenon is called asymmetric division. The other daughters of HSCs (myeloid and lymphoid progenitor cells) can follow any of the othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Practopoiesis
An adaptive system is a set of interacting or interdependent entities, real or abstract, forming an integrated whole that together are able to respond to environmental changes or changes in the interacting parts, in a way analogous to either continuous physiological homeostasis or evolutionary adaptation in biology. Feedback loops represent a key feature of adaptive systems, such as ecosystems and individual organisms; or in the human world, communities, organizations, and families. Adaptive systems can be organized into a hierarchy. Artificial adaptive systems include robots with control systems that utilize negative feedback to maintain desired states. The law of adaptation The law of adaptation may be stated informally as: Formally, the law can be defined as follows: Given a system S, we say that a physical event E is a stimulus for the system S if and only if the probability P(S \rightarrow S', E) that the system suffers a change or be perturbed (in its elements or in i ...

Allopoiesis
Allopoiesis is the Process (industrial), process whereby a system produces something other than the system itself. One example of this is an assembly line, where the final product (such as a car) is distinct from the machines doing the producing. This is in contrast with autopoiesis. wiktionary:allopoiesis, Allopoiesis is a compound word formed from wiktionary:allo-, allo- (Greek prefix meaning other or different) and wiktionary:-poiesis, -poiesis (Greek suffix meaning production, creation or formation).

Blood Cells
A blood cell, also called a hematopoietic cell, hemocyte, or hematocyte, is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Together, these three kinds of blood cells add up to a total 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma, the liquid component of blood. Red blood cells Red blood cells or ''erythrocytes'', primarily carry oxygen and collect carbon dioxide through the use of hemoglobin. Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. Red blood cells are the most abundant cell in the blood, accounting for about 40-45% of its volume. Red blood cells are circular, biconcave, disk-shaped and deformable to allow them to squeeze ...

Zoopoetics
Zoopoetics has been defined as "the process of discovering innovative breakthroughs in form through an attentiveness to another species' bodily ''poiesis''." It assumes many actual, biological animals possess agency to craft gestures, vocalizations—clear material signs—in order to create social cohesion with conspecifics and other animals. Zoopoetics is not a minor event in poetry, nor is it limited to human spheres. Other species discover innovative forms of their bodily ''poiesis'', through, at times, an attentiveness towards humans. Many disciplines have contributed to the radical revaluation of the animal in culture and society; zoopoetics further contributes through tracing the implications of Whitman's insight, that animals, including humans, follow the "same old law" of a bodily ''poiesis''. Usage Jacques Derrida first used the term in ''The Animal that Therefore I Am'' (an address first delivered in 1997), speaking of "Kafka's vast zoopoetics". And so, in the br ...

Plato
Plato ( ; grc-gre, Πλάτων ; 428/427 or 424/423 – 348/347 BC) was a Greek philosopher born in Athens during the Classical period in Ancient Greece. He founded the Platonist school of thought and the Academy, the first institution of higher learning on the European continent. Along with his teacher, Socrates, and his student, Aristotle, Plato is a central figure in the history of Ancient Greek philosophy and the Western and Middle Eastern philosophies descended from it. He has also shaped religion and spirituality. The so-called neoplatonism of his interpreter Plotinus greatly influenced both Christianity (through Church Fathers such as Augustine) and Islamic philosophy (through e.g. Al-Farabi). In modern times, Friedrich Nietzsche diagnosed Western culture as growing in the shadow of Plato (famously calling Christianity "Platonism for the masses"), while Alfred North Whitehead famously said: "the safest general characterization of the European philosophical tradit ...

Poetry
Poetry (derived from the Greek ''poiesis'', "making"), also called verse, is a form of literature that uses aesthetic and often rhythmic qualities of language − such as phonaesthetics, sound symbolism, and metre − to evoke meanings in addition to, or in place of, a prosaic ostensible meaning. A poem is a literary composition, written by a poet, using this principle. Poetry has a long and varied history, evolving differentially across the globe. It dates back at least to prehistoric times with hunting poetry in Africa and to panegyric and elegiac court poetry of the empires of the Nile, Niger, and Volta River valleys. Some of the earliest written poetry in Africa occurs among the Pyramid Texts written during the 25th century BCE. The earliest surviving Western Asian epic poetry, the '' Epic of Gilgamesh'', was written in Sumerian. Early poems in the Eurasian continent evolved from folk songs such as the Chinese ''Shijing'', as well as religious hymns (the S ...

Ecopoetics
Ecopoetry is poetry with a strong ecological emphasis or message. Many poets, poems and books of poems have expressed ecological concerns; but only recently has the term ''ecopoetry'' gained use. There is now, in English-speaking poetry, a recognisable subgenre of ecopoetry. Prior to the term, a number of poems had ecological messages. Although these poets did not mention the word, they were clearly 'Ecopoetic' in stance and exerted an influence on the subsequent subgenre. Examples include: the book ''Ecopoemas'' of Nicanor Parra (1982), ''The White Poem'' by Jay Ramsay & Carole Bruce (Rivelin Grapheme Press, 1988), ''Bosco'' (Hearing Eye, 1999; 2001) and (more recently) ''Heavy Water: a poem for Chernobyl'' (Enitharmon Press, 2004). Early publications also include ''The Green Book of Poetry'' by Ivo Mosley (1995, Frontier Publishing and Harper San Francisco, 1996 as ''Earth Poems ''). It includes over three hundred poems from around the world, many translated by Mosley, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
