Irrelevance Principle
Relevance is the concept of one topic being connected to another topic in a way that makes it useful to consider the second topic when considering the first. The concept of relevance is studied in many different fields, including cognitive sciences, logic, and library and information science. Most fundamentally, however, it is studied in epistemology (the theory of knowledge). Different theories of knowledge have different implications for what is considered relevant and these fundamental views have implications for all other fields as well. Definition "Something (A) is relevant to a task (T) if it increases the likelihood of accomplishing the goal (G), which is implied by T." (Hjørland & Sejer Christensen, 2002). A thing might be relevant, a document or a piece of information may be relevant. The basic understanding of relevance does not depend on whether we speak of "things" or "information". For example, the Gandhian principles are of great relevance in today's world. Ep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Premise
A premise or premiss is a true or false statement that helps form the body of an argument, which logically leads to a true or false conclusion. A premise makes a declarative statement about its subject matter which enables a reader to either agree or disagree with the premise in question, and in doing so understand the logical assumptions of the argument. If a premise is logically false, then the conclusion, which follows from all of the premises of the argument, must also be false—unless the conclusion is supported by a logically valid argument which the reader agrees with. Therefore, if the reader disagrees with any one of the argument's premises, they have a logical basis to reject the conclusion of the argument. Explanation In logic, an argument requires a set of at least two declarative sentences (or "propositions") known as the "premises" (or "premisses"), along with another declarative sentence (or "proposition"), known as the conclusion. This structure of two prem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precision And Recall
In pattern recognition, information retrieval, object detection and classification (machine learning), precision and recall are performance metrics that apply to data retrieved from a collection, corpus or sample space. Precision (also called positive predictive value) is the fraction of relevant instances among the retrieved instances, while recall (also known as sensitivity) is the fraction of relevant instances that were retrieved. Both precision and recall are therefore based on relevance. Consider a computer program for recognizing dogs (the relevant element) in a digital photograph. Upon processing a picture which contains ten cats and twelve dogs, the program identifies eight dogs. Of the eight elements identified as dogs, only five actually are dogs (true positives), while the other three are cats (false positives). Seven dogs were missed (false negatives), and seven cats were correctly excluded (true negatives). The program's precision is then 5/8 (true positives / se ...

Distraction
Distraction is the process of diverting the attention of an individual or group from a desired area of focus and thereby blocking or diminishing the reception of desired information. Distraction is caused by: the lack of ability to pay attention; lack of interest in the object of attention; or the great intensity, novelty or attractiveness of something other than the object of attention. Distractions come from both external sources, and internal sources. External distractions include factors such as visual triggers, social interactions, music, text messages, and phone calls. There are also internal distractions such as hunger, fatigue, illness, worrying, and daydreaming. Both external and internal distractions contribute to the interference of focus. In the car Distracted driving is a dangerous threat to road safety across the world. While drunk driving rates have been on the decline since 1983, distracted driving has been increasing in recent years. Many feel this incline is ...

Description
Description is the pattern of narrative development that aims to make vivid a place, object, character, or group. Description is one of four rhetorical modes (also known as ''modes of discourse''), along with exposition, argumentation, and narration. In practice it would be difficult to write literature that drew on just one of the four basic modes. As a fiction-writing mode Fiction-writing also has modes: action, exposition, description, dialogue, summary, and transition. Author Peter Selgin refers to ''methods'', including action, dialogue, thoughts, summary, scenes, and description. Currently, there is no consensus within the writing community regarding the number and composition of fiction-writing modes and their uses. Description is the fiction-writing mode for transmitting a mental image of the particulars of a story. Together with dialogue, narration, exposition, and summarization, description is one of the most widely recognized of the fiction-writing modes. As state ...

Source Criticism
Source criticism (or information evaluation) is the process of evaluating an information source, i.e.: a document, a person, a speech, a fingerprint, a photo, an observation, or anything used in order to obtain knowledge. In relation to a given purpose, a given information source may be more or less valid, reliable or relevant. Broadly, "source criticism" is the interdisciplinary study of how information sources are evaluated for given tasks. Meaning Problems in translation: The Danish word ''kildekritik'', like the Norwegian word ''kildekritikk'' and the Swedish word ''källkritik'', derived from the German ''Quellenkritik'' and is closely associated with the German historian Leopold von Ranke (1795–1886). Historian Wolfgang Hardtwig wrote: His anke'sfirst work ''Geschichte der romanischen und germanischen Völker von 1494–1514'' (History of the Latin and Teutonic Nations from 1494 to 1514) (1824) was a great success. It already showed some of the basic charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Issues
A social issue is a problem that affects many people within a society. It is a group of common problems in present-day society and ones that many people strive to solve. It is often the consequence of factors extending beyond an individual's control. Social issues are the source of conflicting opinions on the grounds of what is perceived as morally correct or incorrect personal life or interpersonal social life decisions. Social issues are distinguished from economic issues; however, some issues (such as immigration) have both social and economic aspects. Some issues do not fall into either category, such as warfare. There can be disagreements about what social issues are worth solving, or which should take precedence. Different individuals and different societies have different perceptions. In ''Rights of Man and Common Sense'', Thomas Paine addresses the individual's duty to "allow the same rights to others as we allow ourselves." The failure to do so causes the creation of a so ...

Medieval Poetry
Poetry took numerous forms in medieval Europe, for example, lyric and epic poetry. The troubadours and the minnesänger are known for their lyric poetry about courtly love. Among the most famous of secular poetry is ''Carmina Burana'', a manuscript collection of 254 poems. Twenty-four poems of ''Carmina Burana'' were later set to music by German composer Carl Orff in 1936. Examples of medieval poetry Old English religious poetry includes the poem ''Christ'' by Cynewulf and the poem ''The Dream of the Rood'', preserved in both manuscript form and on the Ruthwell Cross. We do have some secular poetry; in fact a great deal of medieval literature was written in verse, including the Old English epic '' Beowulf''. Scholars are fairly sure, based on a few fragments and on references in historic texts, that much lost secular poetry was set to music, and was spread by traveling minstrels, or bards, across Europe. Thus, the few poems written eventually became ballads or lays, and never ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Development
In the economics study of the public sector, economic and social development is the process by which the economic well-being and quality of life of a nation, region, local community, or an individual are improved according to targeted goals and objectives. The term has been used frequently in the 20th and 21st centuries, but the concept has existed in the West for far longer. " Modernization", "Westernization", and especially "industrialization" are other terms often used while discussing economic development. Historically, economic development policies focused on industrialization and infrastructure; since the 1960s, it has increasingly focused on poverty reduction. Whereas economic development is a policy intervention aiming to improve the well-being of people, economic growth is a phenomenon of market productivity and increases in GDP; economist Amartya Sen describes economic growth as but "one aspect of the process of economic development". Economists primarily focus on the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Famine
A famine is a widespread scarcity of food, caused by several factors including war, natural disasters, crop failure, Demographic trap, population imbalance, widespread poverty, an Financial crisis, economic catastrophe or government policies. This phenomenon is usually accompanied or followed by regional malnutrition, starvation, epidemic, and increased death, mortality. Every inhabited continent in the world has experienced a period of famine throughout history. In the 19th and 20th century, generally characterized Southeast and South Asia, as well as Eastern and Central Europe, in terms of having suffered most number of deaths from famine. The numbers dying from famine began to fall sharply from the 2000s. Since 2010, Africa has been the most affected continent of famine in the world. Definitions According to the United Nations World Food Programme, famine is declared when malnutrition is widespread, and when people have started dying of starvation through lack of access to suf ...

Social Justice
Social justice is justice in terms of the distribution of wealth, opportunities, and privileges within a society. In Western and Asian cultures, the concept of social justice has often referred to the process of ensuring that individuals fulfill their societal roles and receive their due from society. In the current movements for social justice, the emphasis has been on the breaking of barriers for social mobility, the creation of safety nets, and economic justice. Social justice assigns rights and duties in the institutions of society, which enables people to receive the basic benefits and burdens of cooperation. The relevant institutions often include taxation, social insurance, public health, public school, public services, labor law and regulation of markets, to ensure distribution of wealth, and equal opportunity. Interpretations that relate justice to a reciprocal relationship to society are mediated by differences in cultural traditions, some of which emphasize t ...
