Hydra Effect
The hydra effect or hydra paradox owes its name to the Greek legend of the Lernaean Hydra which grew two heads for each one cut off, and is used figuratively for counter-intuitive effects of actions to reduce a problem which result in stimulating its multiplication. Most notably, scientists have proposed that ecological systems can exhibit a hydra effect when "a higher death rate in a particular species ultimately increases the size of its population". The hypothesis is suggested to have implications for the eradication of pests, and resource management. There are also said to be indications that reducing the death rate can shrink a population. The hydra effect has also been used about negative outcomes when shutting down torrent sites which come back in more incarnations, and is cited by those opposing the war on drugs and targeted killing as counter-productive effects. In 2016 the site Torrentz shut down its operations without further information for the cause of the shut-do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greek Legend
A major branch of classical mythology, Greek mythology is the body of myths originally told by the ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the origin and nature of the world, the lives and activities of deities, heroes, and mythological creatures, and the origins and significance of the ancient Greeks' own cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral-poetic tradition most likely by Minoan and Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its aftermath became part of the oral tradition of Homer's epic poems, the ''Iliad'' and the ''Odyssey''. Two poems by Homer's near contemporary Hesiod, the ''Theogony'' and the ''Works and Days'', contain accounts of the genesis of the wor ...

Lernaean Hydra
The Lernaean Hydra or Hydra of Lerna ( grc-gre, Λερναῖα Ὕδρα, ''Lernaîa Hýdra''), more often known simply as the Hydra, is a snake, serpentine water monster in Greek mythology, Greek and Roman mythology. Its lair was the lake of Lerna in the Argolid, which was also the site of the myth of the Danaïdes. Lerna was reputed to be an entrance to the Hades, Underworld, and archaeology has established it as a sacred site older than Mycenaean civilization, Mycenaean Argos, Peloponnese, Argos. In the canonical Hydra myth, the monster is killed by Heracles (Hercules) as the second of his Labours of Hercules, Twelve Labors. According to Hesiod, the Hydra was the offspring of Typhon and Echidna (mythology), Echidna. It had poisonous breath and blood so virulent that even its scent was deadly. The Hydra possessed Polycephaly, many heads, the exact number of which varies according to the source. Later versions of the Hydra story add a Regeneration (biology), regeneration feature ...

Torrent Site
A BitTorrent tracker is a special type of server that assists in the communication between peers using the BitTorrent protocol. In peer-to-peer file sharing, a software client on an end-user PC requests a file, and portions of the requested file residing on peer machines are sent to the client, and then reassembled into a full copy of the requested file. The "tracker" server keeps track of where file copies reside on peer machines, which ones are available at time of the client request, and helps coordinate efficient transmission and reassembly of the copied file. Clients that have already begun downloading a file communicate with the tracker periodically to negotiate faster file transfer with new peers, and provide network performance statistics; however, after the initial peer-to-peer file download is started, peer-to-peer communication can continue without the connection to a tracker. Modern BitTorrent clients may implement a distributed hash table and the peer exchange p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War On Drugs
The war on drugs is a global campaign, led by the United States federal government, of drug prohibition, military aid, and military intervention, with the aim of reducing the illegal drug trade in the United States.Cockburn and St. Clair, 1998: Chapter 14 The initiative includes a set of drug policies that are intended to discourage the production, distribution, and consumption of psychoactive drugs that the participating governments and the United Nations have made illegal. The term was popularized by the media shortly after a press conference given on June 18, 1971, by President Richard Nixon—the day after publication of a special message from President Nixon to the Congress on Drug Abuse Prevention and Control—during which he declared drug abuse "public enemy number one". That message to the Congress included text about devoting more federal resources to the "prevention of new addicts, and the rehabilitation of those who are addicted" but that part did not receive ...

Targeted Killing
Targeted killing is a form of murder or assassination carried out by governments outside a judicial procedure or a battlefield. Since the late 20th century, the legal status of targeted killing has become a subject of contention within and between various nations. Historically, at least since the mid-eighteenth century, Western thinking has generally considered the use of assassination as a tool of statecraft to be illegal. Some academics, military personnel and officials describe targeted killing as legitimate within the context of self-defense, when employed against terrorists or combatants engaged in asymmetrical warfare. They argue that drones are more humane and more accurate than manned vehicles, and that targeted or "named killings" do not occur in any context other than a declared state of war. Scholars are also divided as to whether targeted killings are an effective counterterrorism strategy. Africa Targeted killings have also been used in Somalia, Kenya, Rwanda and ...

Torrentz
Torrentz was a Finland-based metasearch engine for BitTorrent, run by an individual known as Flippy, and founded on 24 July 2003. It indexed torrents from various major torrent websites, and offered compilations of various trackers per torrent that were not necessarily present in the default .torrent file, so that when a tracker was down, other trackers could do the work. It was the second most popular torrent website in 2012. Usage Torrentz's user interface was simple; it had only a user menu and a search panel. Users were not required to register before searching files. To perform a search, users would simply type in a string of keywords within the autocomplete-enabled search field and execute the search by either pressing the search button in the UI or the enter key on the keyboard. From there, a list of matching torrent files were displayed on the screen for the user to choose from. This list could be filtered by age (one day, three days, one week or one month) and ...

The Pirate Bay
The Pirate Bay (sometimes abbreviated as TPB) is an online index of digital content of entertainment media and software. Founded in 2003 by Swedish think tank Piratbyrån, The Pirate Bay allows visitors to search, download, and contribute magnet links and torrent files, which facilitate peer-to-peer, file sharing among users of the BitTorrent protocol. The Pirate Bay has sparked controversies and discussion about legal aspects of file sharing, copyright, and civil liberties and has become a platform for political initiatives against established intellectual property laws as well as a central figure in an anti-copyright movement. The website has faced several shutdowns and domain seizures, switching to a series of new web addresses to continue operating. In April 2009, the website's founders ( Peter Sunde, Fredrik Neij, and Gottfrid Svartholm) were found guilty in the Pirate Bay trial in Sweden for assisting in copyright infringement and were sentenced to serve one ye ...

Braess's Paradox
Braess's paradox is the observation that adding one or more roads to a road network can slow down overall traffic flow through it. The paradox was discovered by the German mathematician Dietrich Braess in 1968. The paradox may have analogies in electrical power grids and biological systems. It has been suggested that, in theory, the improvement of a malfunctioning network could be accomplished by removing certain parts of it. The paradox has been used to explain instances of improved traffic flow when existing major roads are closed. Discovery and definition Dietrich Braess, a mathematician at Ruhr University, Germany, noticed the flow in a road network could be impeded by adding a new road, when he was working on traffic modelling. His idea was that if each driver is making the optimal self-interested decision as to which route is quickest, a shortcut could be chosen too often for drivers to have the shortest travel times possible. More formally, the idea behind Braess's di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paradox Of Enrichment
The paradox of enrichment is a term from population ecology coined by Michael Rosenzweig in 1971. He described an effect in six predator–prey models where increasing the food available to the prey caused the predator's population to destabilize. A common example is that if the food supply of a prey such as a rabbit is overabundant, its population will grow unbounded and cause the predator population (such as a lynx) to grow unsustainably large. That may result in a crash in the population of the predators and possibly lead to local eradication or even species extinction. The term 'paradox' has been used since then to describe this effect in slightly conflicting ways. The original sense was one of irony; by attempting to increase the carrying capacity in an ecosystem, one could fatally imbalance it. Since then, some authors have used the word to describe the difference between modelled and real predator–prey interactions. Rosenzweig used ordinary differential equation models ...

Streisand Effect
Attempts to hide, remove, or censor information often have the unintended consequence of increasing awareness of that information via the Internet. This is called the Streisand effect. It is named after American singer and actress Barbra Streisand, whose attempt to suppress the California Coastal Records Project's photograph of her cliff-top residence in Malibu, California, taken to document California coastal erosion, inadvertently drew greater attention to the photograph in 2003. Attempts to suppress information are often made through cease-and-desist letters, but instead of being suppressed, the information receives extensive publicity, as well as media extensions such as videos and spoof songs, which can be mirrored on the Internet or distributed on file-sharing networks. In addition, seeking or obtaining an injunction to prohibit something from being published or remove something that is already published can lead to increased publicity of the published work.
