Information pollution is the contamination of information supply with irrelevant, redundant, unsolicited and low-value information. The spread of useless and undesirable information can have a detrimental effect on human activities. It is considered one of the adverse effects of the information revolution. Pollution is a large problem and is growing rapidly in e-mail, instant messaging (IM), and RSS feeds.
The term acquired particular relevance in 2003 when Jakob Nielsen, a leading web usability expert, published a number of articles discussing the topic. However, as early as 1971 researchers were expressing doubts about the negative effects of having to recover ‘valuable nodules from a slurry of garbage in which it is a randomly dispersed minor component.’ Continue reading

Information Revolution
The term information revolution describes current economic, social, and technological trends beyond the Industrial Revolution. Many competing terms have been proposed that focus on different aspects of this societal development.
The British polymath crystallographer J. D. Bernal introduced the term ‘scientific and technical revolution’ in his book ‘The Social Function of Science’ (1939) in order to describe the new role that science and technology are coming to play within society. He asserted that science is becoming a ‘productive force,’ using the Marxist Theory of Productive Forces (a widely-used concept in communism placing primary emphasis on technical advances and strong productive forces in a nominally socialist economy before real communism, or even real socialism, can have a hope of being achieved).

Technological Unemployment
Technological unemployment is unemployment primarily caused by technological change. Since the early 1800’s, the observation of economists has been that technology has had a positive influence on employment: as technological change increased productivity, prices for commodities fell, resulting in increased demand, thereby increasing demand for labor. Machines freed workers from simple manual work but created new better paying jobs requiring more specialized skills.
However, some technologists claim that modern capabilities of pattern recognition, machine learning, and global networking are steadily eliminating the skilled work of large swaths of the middle income workforce. The warning is that technology is no longer creating jobs at the rate that it is making others obsolete. The notion of technological unemployment leading to structural unemployment (and being macroeconomically injurious) is often dismissed as the ‘Luddite fallacy.’ Continue reading
Boom and Bust
A credit boom-bust cycle is an episode characterized by a sustained increase in several economics indicators followed by a sharp and rapid contraction. Commonly the boom is driven by a rapid expansion of credit to the private sector accompanied with rising prices of commodities and stock market index.
Following the boom phase, asset prices collapse and a credit crunch arises, where access to financing opportunities are sharply reduced below levels observed during normal times. The unwinding of the boom phase brings a considerably large reduction in investment and fall in consumption and an economic recession may follow. The recession following the burst of the episode is oftentimes short-lived, GDP and consumption growth usually resume within a year.
Malthusian Catastrophe
A Malthusian catastrophe [mal-thoo-zee-uhn] would be a forced return to subsistence-level conditions due to population growth outpacing agricultural production. Population and growth size has a negative impact on the environment. Later formulations consider economic growth limits as well. The term is also commonly used in discussions of oil depletion. Based on the work of political economist Thomas Malthus (1766–1834), theories of Malthusian catastrophe are very similar to the Iron Law of Wages (real wages always tend toward the minimum wage necessary to sustain the life of the worker).
The main difference is that the Malthusian theories predict what will happen over several generations or centuries, whereas the Iron Law of Wages predicts what will happen in a matter of years and decades. The Industrial Revolution enabled the modern world to break out of the Malthusian growth model, however, various limited resources which may soon limit human population growth because of a widespread belief in the importance of prosperity for every individual and the rising consumption trends of large developing nations such as China and India.
Iron Law of Wages
The Iron Law of Wages is a proposed law of economics that asserts that real wages always tend, in the long run, toward the minimum wage necessary to sustain the life of the worker. The theory was first named by Ferdinand Lassalle in the mid-nineteenth century.
Karl Marx attributed the doctrine to Lassalle (notably in ‘Critique of the Gotha Programme’), crediting the idea to Thomas Malthus in his work, ‘An Essay on the Principle of Population,’ and the terminology to Goethe’s ‘great, eternal iron laws’ in ‘Das Göttliche’ (‘On the Divine’).

Malthusian Trap
The Malthusian trap [mal-thoo-zee-uhn], named after political economist Thomas Robert Malthus, suggests that for most of human history, income was largely stagnant because technological advances and discoveries only resulted in more people, rather than improvements in the standard of living.
It is only with the onset of the Industrial Revolution in about 1800 that the income per person dramatically increased, and they broke out of the Trap; it has been shown, however, that the escape from the Malthusian trap can also generate serious political upheavals.
Papel Picado
Papel picado (‘perforated paper’) is a decorative craft made out of paper cut into elaborate designs. Although it is a Mexican folk art, papel picado is used as a holiday decoration in many countries. The designs are commonly cut from tissue paper using a guide and small chisels, creating as many as forty banners at a time. Common themes includes birds, floral designs, and skeletons.
They are commonly displayed for both secular and religious occasions, such as Easter, Christmas, the Day of the Dead, as well as during weddings, quinceañeras, baptisms, and christenings. In Mexico, papel picado is especially incorporated into altars during the Day of the Dead. Continue reading
La Calavera Catrina
La Calavera Catrina (‘The Elegant Skull’) is a 1910 zinc etching by Mexican printmaker José Guadalupe Posada, part of his series of calaveras (humorous images of contemporary figures depicted as skeletons, which often were accompanied by a poem). The image has since become a staple of Mexican imagery, and often is incorporated into artistic manifestations of the Day of the Dead in November, such as altars and calavera costumes. Although these holy days have a long cultural history reaching into the prehistoric traditions of several European cultures, many aspects of the Mexican festival have indigenous origins in an Aztec festival dedicated to the goddess Mictecacihuatl. After the conquest of Mexico, the Spanish superimposed their cultural traditions upon the similar Aztec festival and a synthesis occurred.
‘La Catrina,’ as it is commonly known, was a popular print in Posada’s day, but soon faded from the popular memory. Along with the rest of Posada’s prints, it was revived by French artist and art historian Jean Charlot shortly after the Mexican Revolution in the 1920s. ‘La Catrina’ soon gained iconic status as a symbol of uniquely Mexican art and was reproduced en masse. The image was incorporated into Diego Rivera’s mural ‘Dream of a Sunday’in Alameda Park,’ which also includes images of his wife Frida Kahlo, Posada, and a self-portrait of Rivera. Notable paper cutter Marcelino Bautista Sifuentes has also recreated the famous ‘La Calavera Catrina’ in papel picado (a decorative craft made out of paper cut into elaborate designs).
Calaca
A calaca [kal-ah-kuh] (a colloquial Mexican Spanish name for skeleton) is a figure of a skull or skeleton (usually human) commonly used for decoration during the Mexican Day of the Dead festival, although they are made all year round. Tracing their origins from Aztec imagery, calacas are frequently shown with marigold flowers and foliage. As with other aspects of the Day of the Dead festival, calacas are generally depicted as joyous rather than mournful figures. They are often shown wearing festive clothing, dancing, and playing musical instruments to indicate a happy afterlife. This draws on the Mexican belief that no dead soul likes to be thought of sadly, and that death should be a joyous occasion. This goes back to Aztec beliefs, one of the few traditions to remain after the Spanish conquest.
Calacas used in the festival include carved skull masks worn by revelers, small figures made out of carved wood or fired clay, and sweet treats in the form of skulls or skeletons. Calacas are sometimes made of wood, stone, or even candy. A popular phrase among Mexicans and those Latinos that personally know some is ‘se lo (la) llevo la calaca’ after someone has died, literally meaning ‘the Calaca took him (her)’ or ‘death took him (her).’ In Guatemala, ‘calaca’ is understood as ‘death’ and implies fear of death. Thus, it is not depicted as a joyful image. Calaca-like figures can be seen in the Tim Burton films ‘The Nightmare Before Christmas’ and ‘Corpse Bride,’ the 2008 PlayStation 3 game ‘LittleBigPlanet,’ and the 1998 Tim Schafer computer game ‘Grim Fandango.’
Transculturation
Transculturation [trans-kuhl-chuh-rey-shuhn] is a term coined by Cuban anthropologist Fernando Ortiz in 1940 to describe the phenomenon of merging and converging cultures. Transculturation encompasses more than transition from one culture to another; it does not consist merely of acquiring another culture (acculturation) or of losing or uprooting a previous culture (deculturation).
Rather, it merges these concepts and additionally carries the idea of the consequent creation of new cultural phenomena (neoculturation). Ortiz also referred to the devastating impact of Spanish colonialism on Cuba’s indigenous peoples as a ‘failed transculturation.’ Transculturation can often be the result of colonial conquest and subjugation, especially in a postcolonial era as native peoples struggle to regain their own sense of identity.
Cosmopolitanism
Cosmopolitanism [koz-muh-pol-i-tn-iz-uhm] is the ideology that all kinds of human ethnic groups belong to a single community based on a shared morality. This is contrasted with communitarianism, which emphasizes the need to balance individual rights and interests with that of the community as a whole, and argues that individual people are shaped by the cultures and values of their communities.
Cosmopolitanism may entail some sort of world government or it may simply refer to more inclusive moral, economic, and/or political relationships between nations or individuals of different nations. The word derives from Greek ‘cosmos’ (‘the Universe’) and ‘polis’ (‘city’).
