DELTA DEscription Language for TAxonomy is a data format used in alpha taxonomytaxonomy for recording descriptions of living things. It is designed for computer processing, allowing the generation of identification keys, diagnosis , etc. It is widely accepted as a standard, one of only a few such standards. Quite a bit of software is available for various tasks, using this format. There is a website on DELTA, linking to many databases in this format. It was devised the CSIRO Australian Division of Entomology in 1971 to 2000, with a notable part taken by Dr. Michael J. Dallwitz.

Unreferenced date June 2009 Plant taxonomy is the science that finds, describes, classifies, identifies, and names plant s. It thus is one of the main branches of alpha taxonomytaxonomy . Plant taxonomy is closely allied to history of plant systematics plant systematics , and there is no sharp boundary between the two. In practice, plant systematics is involved with relationships between plants and their evolution, especially at the higher levels, whereas plant taxonomy deals with the actual handling of plant specimen s. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally there is no really close agreement on wiktionary circumscription circumscription and placement of taxon taxa . See the list of systems of plant taxonomy . Identification and classification Two goals of plant taxonomy are the identification and classification of plants. The distinction between these two goals is important and often overlooked. Plant identification is the determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals. The process of identification connects the specimen with a published name. Once a plant specimen has been identified, its name and properties are known. Plant classification is the placing of known plants into groups or categories to show some relationship. Scientific classification follows a system of rules that standardizes the results, and groups successive categories into a hierarchy . For example, the Family biology family to which the Lilium lilies belong is classified as follows Kingdom Plant ae Division Magnoliophyta Class Liliopsida Order Liliales ...

Numerical taxonomy is a Biological classification classification system in biological systematics which deals with the grouping by numerical method s of taxon taxonomic units based on their character states. ref cite web url http www.accessscience.com abstract.aspx?id 461900&referURL http 3a 2f 2fwww.accessscience.com 2fcontent.aspx 3fid 3d461900 title Numerical Taxonomy author date work www.accessscience.com publisher McGraw Hill Ltd. accessdate 13 April 2010 ref . It aims to create a taxonomy using numeric algorithms like cluster analysis rather than using subjective evaluation of their properties. The concept was first developed by Robert R. Sokal & Peter H.A. Sneath in 1963 ref Sokal & Sneath Principles of Numerical Taxonomy , San Francisco W.H. Freeman, 1963 ref and later elaborated by the same authors ref Sneath and Sokal Numerical Taxonomy , San Francisco W.H. Freeman, 1973 ref . They divided the field into phenetics in which classifications are formed based on the patterns of overall similarities and cladistics in which classifications based on the branching patterns of the estimated evolutionary history of the taxa. Note in recent years many authors treat numerical taxonomy and phenetics as synonyms despite the distinctions made by those authors. Although intended as an objective classification method, in practice the choice and implicit weighing of characteristics is, of course, influenced by available data and research interests of the investigator. What was made objective was the introduction of explicit steps to be used to create phenograms and cladograms using numerical methods rather than subjective synthesis of data.

Unreferenced date December 2009 In taxonomy , inclusion is the process whereby two species that were believed to be distinct are found in fact to be the same and are thus combined as one species. Which name is kept for this unified species is sometimes a cause of debate, but generally it is the earlier named one, and the other species is said to be included within this one. Inclusion is far more common in paleontology than more recent biology , although it is not unheard of in the latter. When it occurs with more recent or modern species, it is usually the result of a species with wide geographical dispersion.

Corporate taxonomy is the hierarchical classification of entities of interest of an enterprise, organization or administration, used to classify documents, digital assets and other information. Taxonomies can cover virtually any type of physical or conceptual entities products, processes, knowledge fields, human groups, etc. at any level of granularity . Corporate taxonomies are increasingly used in information systems particularly content management and knowledge management systems , as a way to allow instant access to the right information within exponentially growing volumes of data in learning organizations . Relatively simple systems based on semantic networks and taxonomies proved to be a serious competitor to heavy data mining systems and behavior analysis software in contextual filtering applications used for routing customer requests, pushing content on a Web site or delivering product advertising in a targeted and pertinent way. A powerful approach to map and retrieve unstructured data, taxonomies allow efficient solutions in the management of corporate knowledge, in particular in complex organizational models for workflows , human resources or customer relations . As an extension of traditional thesauri and Taxonomic classification classifications used in a company, a corporate taxonomy is usually the fruit of a large harmonization effort involving most departments of the organization.

In Alpha taxonomytaxonomy , a segregate , or a segregate taxon is created when a taxon is split off, from another taxon. This other taxon will be better known, usually bigger, and will continue to exist, even after the segregate taxon has been split off. A segregate will be either new or ephemeral there is a tendency for taxonomists to disagree on segregates, and later workers often reunite a segregate with the mother taxon. If a segregate is generally accepted as a good taxon it ceases to be a segregate. Thus, this is a way of indicating change in the taxonomic status. It should not be confused with, for example, the subdivision of a genus into subgenus subgenera . For example, the genus Alsobia is a segregate from the genus Episcia The genera Filipendula and Aruncus are segregates from the genus Spiraea .

The first four levels are essentially cognitive thinking , while the last four levels are affective feeling in nature. Each level of the Taxonomy is taught explicitly to students so that students are trained in creative thinking skills. Once familiar with each skill, students are given opportunity to transfer skill to content. The eight levels are Fluency, the generation of many ideas, answers, responses , possibilities to a given situation problem Flexibility, the generation of alternatives, variations, adaptations, different ideas solutions options Originality, the generation of new, unique and novel responses solutions Elaboration, the expansion, enlargement, enrichment or embellishment of ideas to make it easier for others to understand or make it more interesting Risk taking, experimenting, trying new challenges Complexity, the ability to create structure out of chaos, to bring logical order to a given situation and or to see the missing parts Curiosity, the ability to wonder, ponder, contemplate or puzzle Imagination, the ability to build mental pictures, visualise possibilities and new things or reach beyond practical limits. The purposes of the taxonomy are to teach creative thinking skills, to encourage lateral thinking as well as proactivity, to foster creativity, and to develop students creative talents which can be transferred to the changing challenges faced in everyday life.

The taxonomy aims to classify innovation modes according to different sectoral groups and the flow of knowledge between such groups. It was first proposed by SPRU researcher Keith Pavitt at the University of Sussex and has since been applied in innovation research to describe and categorize industries and the firms therein Daniele Archibugi Archibugi 2001 .

Sources of innovation may be both internal and external to the firm with a medium level of appropriability. 3 Specialized Suppliers smaller, more specialized firms producing technology to be sold into other firms, e.g. specialized machinery production and high tech instruments.

Evolutionary taxonomy , evolutionary systematics or Darwinian classification is a branch of biological classification that seeks to classify organism s using a combination of Phylogenetics phylogenetic relationship and overall similarity. This type of taxonomy considers taxa rather than single species, so that groups of species give rise to new groups. The concept found its current form in the modern evolutionary synthesis of the early 1940s. Evolutionary taxonomy differs from strict pre Darwinian Linnaean taxonomy , which produces orderly lists rather than Phylogenetic tree trees . Also, unlike cladistics cladism which only maps phylogeny, evolutionary taxonomy also offer a biological biological classification classification system . ref name Mayr Bock 2002 While in phylogeny where each taxon must consist of a single ancestral node and all its descendants, evolutionary taxonomy allows for groups to be excluded from their parent taxa e.g. dinosaurs are not considered to include birds, but to have given rise to them , thus allowing for paraphyly paraphyletic taxa. ref name grant2003 citation url http www.amjbot.org cgi content full 90 9 1263 doi 10.3732 ajb.90.9.1263 title Incongruence between cladistic and taxonomic systems year 2003 author Grant, V. journal American Journal of Botany volume 90 issue 9 page 1263 ref Origin of evolutionary taxonomy File Edward Hitchcock Paleontological ... diagrams are a hallmark of evolutionary taxonomy Linnaean taxonomy was an established discipline when Darwin formulated his theory of evolution .

Unreferenced date October 2010 Human taxonomy is the classification of the species Homo sapiens Latin wise man , or modern human. Homo genus Homo is the human genus , which also includes Neanderthal s and many other extinct species of hominid H. sapiens is the only surviving species of the genus Homo . Extinct Homo species are known as archaic humans. Modern humans are the subspecies Human Homo sapiens sapiens , differentiated from a direct ancestor, Homo sapiens idaltu . Prior to the current scientific classification of humans, philosophers and scientists have made various attempts to classify humans. They offered various definitions of the human being and various schemes for classifying types of humans. Biologists once classified races as subspecies, but today scientists question even the concept of race itself. Certain issues in human taxonomy remain topics of debate today. Extended scientific classification The modern scientific classification of the human species contains many sub and super sections each one being, ideally, a clade which have been interpolated between the seven traditional taxon Linnaean taxonomic ranks . Humans are not only the sole surviving representatives of the genus Homo but also the only surviving representatives of the subtribe Hominina, which includes Australopithecus and other more anthropomorphic hominids.

Flynn s Taxonomy Flynn s taxonomy is a classification of computer architecture s, proposed by Michael J. Flynn in 1966. ref Cite journal last Flynn first M. title Some Computer Organizations and Their Effectiveness journal IEEE Trans. Comput. volume C 21 pages 948 year 1972 ref ref Cite journal last Duncan first Ralph title A Survey of Parallel Computer Architectures journal IEEE Computer year 1990 pages 5 16 doi ref Classifications The four classifications defined by Flynn are based upon the number of concurrent instruction or control and data streams available in the architecture SISD Single Instruction, Single Data stream SISD A sequential computer which exploits no parallelism in either the instruction or data streams. Examples of SISD architecture are the traditional uniprocessor machines like a Personal Computer PC currently manufactured PCs have multiple processors or old Mainframe computer mainframes . SIMD Single Instruction, Multiple Data streams SIMD A computer which exploits multiple data streams against a single instruction stream to perform operations which may be naturally parallelized. For example, an array processor or GPU . MISD Multiple Instruction, Single Data stream MISD Multiple instructions operate on a single data stream. Uncommon architecture which is generally used for fault tolerance. Heterogeneous systems operate on the same data stream and must agree on the result. Examples include the Space Shuttle flight control computer. MIMD Multiple Instruction, Multiple Data streams MIMD Multiple autonomous processors simultaneously executing different instructions on different data. Distributed system s are generally recognized to be MIMD architectures either exploiting a single shared memory space or a distributed memory space.
