Cohort (military Unit)
A cohort (from the Latin ''cohors'', plural ''cohortes'', see wikt:cohors for full inflection table) was a standard tactical military unit of a Roman legion. Although the standard size changed with time and situation, it was generally composed of 480 soldiers. A cohort is considered to be the equivalent of a modern military battalion. The cohort replaced the '' maniple'' following the reforms attributed to Gaius Marius in 107 BC. Shortly after the military reforms of Marius, and until the middle of the third century AD, ten cohorts (about 5,000 men total) made up a legion. Cohorts were named "first cohort,” "second cohort," etc. The first cohort consisted of experienced legionaries, while the legionaries in the tenth cohort were less experienced. Legionary cohort A legionary cohort of the early empire consisted of six ''centuriae'', or centuries, each consisting of 80 legionaries, for a total of 480 legionaries. Prior to the Marian reforms, each ''centuria'' consisted of 100 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cohort Study
A cohort study is a particular form of longitudinal study that samples a cohort (a group of people who share a defining characteristic, typically those who experienced a common event in a selected period, such as birth or graduation), performing a cross-section at intervals through time. It is a type of panel study where the individuals in the panel share a common characteristic. Cohort studies represent one of the fundamental designs of epidemiology which are used in research in the fields of medicine, pharmacy, nursing, psychology, social science, and in any field reliant on 'difficult to reach' answers that are based on evidence (statistics). In medicine for instance, while clinical trials are used primarily for assessing the safety of newly developed pharmaceuticals before they are approved for sale, epidemiological analysis on how risk factors affect the incidence of diseases is often used to identify the causes of diseases in the first place, and to help provide pre-clinica ...

Cohort (educational Group)
A cohort is a Student group, group of students who work through a curriculum together to achieve the same academic degree together. Cohortians are the individual members of such a group. In a cohort, there is an expectation of richness to the learning process due to the multiple perspectives offered by the students. Cohort model A cohort model features a delivery structure that is driven by the expectations, experiences, and beliefs of the cohort's participants. It is usually implemented based on an applicable theory such as the structuration framework. Cohort groups can be organized in such a way that groups of students take a number of similar programs each semester and this organization can change when the term ends so that students can interact with more students. Cohort can be distinguished from groups of students through the following aspects: * cohorts allow school administrators to enroll students en masse while groups only concern teacher management within the class; ...

Cohort (floating Point)
The IEEE 754-2008 standard includes decimal floating-point number formats in which the significand and the exponent (and the payloads of NaNs) can be encoded in two ways, referred to as binary encoding and ''decimal encoding''. Both formats break a number down into a sign bit ''s'', an exponent ''q'' (between ''q''min and ''q''max), and a ''p''-digit significand ''c'' (between 0 and 10''p''−1). The value encoded is (−1)''s''×10''q''×''c''. In both formats the range of possible values is identical, but they differ in how the significand ''c'' is represented. In the decimal encoding, it is encoded as a series of ''p'' decimal digits (using the densely packed decimal (DPD) encoding). This makes conversion to decimal form efficient, but requires a specialized decimal ALU to process. In the binary integer decimal (BID) encoding, it is encoded as a binary number. Format Using the fact that 210 = 1024 is only slightly more than 103 = 1000, 3''n''-digit decimal numbers ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cohort (statistics)
In statistics, marketing and demography, a cohort is a group of subjects who share a defining characteristic (typically subjects who experienced a common event in a selected time period, such as birth or graduation). Cohort data can oftentimes be more advantageous to demographers than period data. Because cohort data is honed to a specific time period, it is usually more accurate. It is more accurate because it can be tuned to retrieve custom data for a specific study. In addition, cohort data is not affected by tempo effects, unlike period data. On the contrary, cohort data can be disadvantageous in the sense that it can take a long amount of time to collect the data necessary for the cohort study. Another disadvantage of cohort studies is that it can be extremely costly to carry out, since the study will go on for a long period of time, demographers often require sufficient funds to fuel the study. Demography often contrasts cohort perspectives and period perspectives. Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cohort (taxonomy)
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two. Consider a particular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cohort Analysis
Cohort analysis is a kind of behavioral analytics that breaks the data in a data set into related groups before analysis. These groups, or cohorts, usually share common characteristics or experiences within a defined time-span. Cohort analysis allows a company to "see patterns clearly across the life-cycle of a customer (or user), rather than slicing across all customers blindly without accounting for the natural cycle that a customer undergoes." By seeing these patterns of time, a company can adapt and tailor its service to those specific cohorts. While cohort analysis is sometimes associated with a cohort study, they are different and should not be viewed as one and the same. Cohort analysis is specifically the analysis of cohorts in regards to big data and business analytics, while in cohort study, data is broken down into similar groups. Examples The goal of business analytics is to analyze and present actionable information. Large, undifferentiated datasets may include a varie ...

Infinite Discs
Infinite Discs is an American disc golf equipment retail company based in Logan, Utah. The company also maintains a disc golf scorekeeping app, a course directory, a round tracking website, and a line of discs. History The company was founded by amateur disc golfer Alan Barker on October 15, 2012 in Logan, Utah. Barker was initially making real estate websites, until one of his employees introduced him to disc golf. They later created Disc Golf Reviewer, a review blog with Amazon and eBay affiliate links. To grow beyond affiliate marketing, Barker looked into ways to better monetize his blog. He considered striking a partnership with Altitude Disc Golf, a local Utah disc golf retailer, but the company was going out of business. He offered to buy it out, but eventually launched Infinite Discs. Company overview Infinite Discs is one of the largest disc golf retailers in the United States, with three brick-and-mortar locations (in Logan, Utah, in Pocatello, Idaho, and in St ...

Cohortes Urbanae
The ''cohortes urbanae'' (Latin meaning ''urban cohorts'') of ancient Rome were created by Augustus to counterbalance the enormous power of the Praetorian Guard in the city of Rome and serve as a police service. They were led by the urban prefect. Duties The gangs of Titus Annius Milo, Publius Clodius and others which were used by rival politicians during the Republic had been eliminated mostly due to the efforts of Pompeius Magnus. Although political gangs were a thing of the past since effective power no longer resided in the competing factions of the Roman Senate and elected officials, some kind of police force was necessary to maintain public order and prevent civil disturbances. To fulfill this purpose Augustus established three urban cohorts (''cohortes urbanae'') under a newly appointed prefect of the city. Their primary role was to police Rome and counteract roaming mobs and gangs that often haunted its streets during the Republic. The urban cohorts thus acted as a heavy ...
