🔗 Alternative education

A Sudbury school is a type of school, usually for the K-12 age range, where students have complete responsibility for their own education, and the school is run by a direct democracy in which students and staff are equal citizens. Students use their time however they wish, and learn as a by-product of ordinary experience rather than through coursework. There is no predetermined educational syllabus, prescriptive curriculum or standardized instruction. This is a form of democratic education. Daniel Greenberg, one of the founders of the original Sudbury Model school, writes that the two things that distinguish a Sudbury Model school are that everyone - adults and children - are treated equally and that there is no authority other than that granted by the consent of the governed.

While each Sudbury Model school operates independently and determines their own policies and procedures, they share a common culture. The intended culture within a Sudbury school has been described with such words as freedom, trust, respect, responsibility and democracy.

The name 'Sudbury' originates from the Sudbury Valley School, founded in 1968 in Framingham, Massachusetts, near Sudbury, Massachusetts. Though there is no formal or regulated definition of a Sudbury Model school, there are now more than 60 schools that identify themselves with Sudbury around the world. Some, though not all, include "Sudbury" in their name. These schools operate as independent entities and are not formally associated in any way.

🔗 Computer science 🔗 Statistics

A Boltzmann machine (also called stochastic Hopfield network with hidden units) is a type of stochastic recurrent neural network. It is a Markov random field. It was translated from statistical physics for use in cognitive science. The Boltzmann machine is based on stochastic spin-glass model with an external field, i.e., a Sherrington–Kirkpatrick model that is a stochastic Ising Model and applied to machine learning.

Boltzmann machines can be seen as the stochastic, generative counterpart of Hopfield networks. They were one of the first neural networks capable of learning internal representations, and are able to represent and (given sufficient time) solve combinatoric problems.

They are theoretically intriguing because of the locality and Hebbian nature of their training algorithm (being trained by Hebb's rule), and because of their parallelism and the resemblance of their dynamics to simple physical processes. Boltzmann machines with unconstrained connectivity have not proven useful for practical problems in machine learning or inference, but if the connectivity is properly constrained, the learning can be made efficient enough to be useful for practical problems.

They are named after the Boltzmann distribution in statistical mechanics, which is used in their sampling function. That's why they are called "energy based models" (EBM). They were invented in 1985 by Geoffrey Hinton, then a Professor at Carnegie Mellon University, and Terry Sejnowski, then a Professor at Johns Hopkins University.

Shit life syndrome (SLS) is a phrase used by physicians in the United Kingdom and the United States for the effect that a variety of poverty or abuse-induced disorders can have on patients.

Sarah O'Connor's 2018 article for the Financial Times "Left behind: can anyone save the towns the economy forgot?" on shit life syndrome in the English coastal town of Blackpool won the 2018 Orwell Prize for Exposing Britain's Social Evils. O'Connor wrote that

Blackpool exports healthy skilled people and imports the unskilled, the unemployed and the unwell. As people overlooked by the modern economy wash up in a place that has also been left behind, the result is a quietly unfolding health crisis. More than a tenth of the town's working-age inhabitants live on state benefits paid to those deemed too sick to work. Antidepressant prescription rates are among the highest in the country. Life expectancy, already the lowest in England, has recently started to fall. Doctors in places such as this have a private diagnosis for what ails some of their patients: "Shit Life Syndrome" ... People with SLS really do have mental or physical health problems, doctors say. But they believe the causes are a tangled mix of economic, social and emotional problems that they — with 10- to 15-minute slots per patient — feel powerless to fix. The relationship between economics and health is blurry, complex and politically fraught. But it is too important to ignore.

In a column for The Irish Times, writer John McManus questioned whether Ireland had developed shit life syndrome in the wake of a recent fall in life expectancy.

A 2018 article in The Quietus on the films of the British director Mike Leigh identified shit life syndrome in Leigh's 2002 film All or Nothing. Kinney wrote that "The film asks questions about poverty – what does poverty do to people? How do you react when the chips are down? ... The rise of populism in this country has been analysed through the lens of the 'left behind' – in a less crude way, this is exactly what All or Nothing was observing sixteen years ago."

Rosemary Rizq, in an essay in the 2016 collection The Future of Psychological Therapy, questioned the origin of the term shit life syndrome, writing that "The phrase seemed to denote a level of long-standing poverty, family breakdown, lack of stability, unemployment and potential risk factors common to many of the predominately young, working class patients referred to the [psychotherapeutic] service" for shit is "something that we continually reject, get rid of or hide. At the same time it is something we cannot completely repudiate, it is part of us, something we need" and that the individuals with SLS have problems so "terrible, so untouchable" that they "quite literally cannot be thought about, cannot be handled by the service", yet a therapeutic organisation is "obliged to do so".

Daphne Anne Caruana Galizia (née Vella; 26 August 1964 – 16 October 2017) was a Maltese writer, journalist, blogger and anti-corruption activist, who reported on political events in Malta. In particular, she focused on investigative journalism, reporting on government corruption, nepotism, patronage, allegations of money laundering, links between Malta's online gambling industry and organized crime, Malta's citizenship-by-investment scheme, and payments from the government of Azerbaijan. Caruana Galizia's national and international reputation was built on her regular reporting of misconduct by Maltese politicians and politically exposed persons.

Caruana Galizia continued to publish articles for decades, despite intimidation and threats, libel suits and other lawsuits. She was arrested by the Malta Police Force on two occasions. Caruana Galizia's investigations were published via her personal blog Running Commentary, which she set up in 2008. She was a regular columnist with The Sunday Times of Malta and later The Malta Independent. Her blog consisted of investigative reporting and commentary, some of which was regarded as personal attacks on individuals, leading to a series of legal battles. In 2016 and 2017, she revealed controversially sensitive information and allegations relating to a number of Maltese politicians and the Panama Papers scandal.

On 16 October 2017, Caruana Galizia was killed close to her home when a car bomb was detonated inside her vehicle, attracting widespread local and international condemnation of the attack. In December 2017, three men were arrested in connection with the car bomb attack. Police arrested Yorgen Fenech, the owner of the Dubai-based company 17 Black, on his yacht on 20 November 2019 in connection with her murder.

In April 2018, an international consortium of 45 journalists published The Daphne Project, a collaboration to complete her investigative work. The GUE/NGL Award for Journalists, Whistleblowers & Defenders of the Right to Information was established in 2018 in honour of Galizia.

HeLa (; also Hela or hela) is an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line. The line was derived from cervical cancer cells taken on February 8, 1951 from Henrietta Lacks, a patient who died of cancer on October 4, 1951. The cell line was found to be remarkably durable and prolific, which gives rise to its extensive use in scientific research.

The cells from Lacks's cancerous cervical tumor were taken without her knowledge or consent, which was common practice at the time. Cell biologist George Otto Gey found that they could be kept alive, and developed a cell line. Previously, cells cultured from other human cells would only survive for a few days. Scientists would spend more time trying to keep the cells alive than performing actual research on them. Cells from Lacks' tumor behaved differently. As was custom for Gey's lab assistant, she labeled the culture 'HeLa', the first two letters of the patient's first and last name; this became the name of the cell line.

These were the first human cells grown in a lab that were naturally "immortal", meaning that they do not die after a set number of cell divisions (i.e. cellular senescence). These cells could be used for conducting a multitude of medical experiments—if the cells died, they could simply be discarded and the experiment attempted again on fresh cells from the culture. This represented an enormous boon to medical and biological research, as previously stocks of living cells were limited and took significant effort to culture.

The stable growth of HeLa enabled a researcher at the University of Minnesota hospital to successfully grow polio virus, enabling the development of a vaccine, and by 1952, Jonas Salk developed a vaccine for polio using these cells. To test Salk's new vaccine, the cells were put into mass production in the first-ever cell production factory.

In 1953, HeLa cells were the first human cells successfully cloned and demand for the HeLa cells quickly grew in the nascent biomedical industry. Since the cells' first mass replications, they have been used by scientists in various types of investigations including disease research, gene mapping, effects of toxic substances on organisms, and radiation on humans. Additionally, HeLa cells have been used to test human sensitivity to tape, glue, cosmetics, and many other products.

Scientists have grown an estimated 50 million metric tons of HeLa cells, and there are almost 11,000 patents involving these cells.

The HeLa cell lines are also notorious for invading other cell cultures in laboratory settings. Some have estimated that HeLa cells have contaminated 10–20% of all cell lines currently in use.

The New Oxford American Dictionary (NOAD) is a single-volume dictionary of American English compiled by American editors at the Oxford University Press.

NOAD is based upon the New Oxford Dictionary of English (NODE), published in the United Kingdom in 1998, although with substantial editing, additional entries, and the inclusion of illustrations. It is based on a corpus linguistics analysis of Oxford's 200 million word database of contemporary American English.

NOAD includes a diacritical respelling scheme to convey pronunciations, as opposed to the Gimson phonemic IPA system that is used in NODE.

In philosophy and mathematics, Newcomb's paradox, also referred to as Newcomb's problem, is a thought experiment involving a game between two players, one of whom is able to be able to predict the future.

Newcomb's paradox was created by William Newcomb of the University of California's Lawrence Livermore Laboratory. However, it was first analyzed in a philosophy paper by Robert Nozick in 1969, and appeared in the March 1973 issue of Scientific American, in Martin Gardner's "Mathematical Games." Today it is a much debated problem in the philosophical branch of decision theory.

South Georgia and the South Sandwich Islands (SGSSI) is a British Overseas Territory in the southern Atlantic Ocean. It is a remote and inhospitable collection of islands, consisting of South Georgia Island and a chain of smaller islands known as the South Sandwich Islands. South Georgia is 165 kilometres (103 mi) long and 35 kilometres (22 mi) wide and is by far the largest island in the territory. The South Sandwich Islands lie about 700 kilometres (430 mi) southeast of South Georgia. The territory's total land area is 3,903 km² (1,507 sq mi). The Falkland Islands are about 1,300 kilometres (810 mi) west from its nearest point.

No permanent native population lives in the South Sandwich Islands, and a very small non-permanent population resides on South Georgia. There are no scheduled passenger flights or ferries to or from the territory, although visits by cruise liners to South Georgia are increasingly popular, with several thousand visitors each summer.

The United Kingdom claimed sovereignty over South Georgia in 1775 and the South Sandwich Islands in 1908. The territory of "South Georgia and the South Sandwich Islands" was formed in 1985; previously, it had been governed as part of the Falkland Islands Dependencies. Argentina claimed South Georgia in 1927 and claimed the South Sandwich Islands in 1938.

Argentina maintained a naval station, Corbeta Uruguay, on Thule Island in the South Sandwich Islands from 1976 until 1982 when it was closed by the Royal Navy. The Argentine claim over South Georgia contributed to the 1982 Falklands War, during which Argentine forces briefly occupied the island. Argentina continues to claim sovereignty over South Georgia and the South Sandwich Islands.

Toothfish are vital to the islands' economy; as a result, Toothfish Day is celebrated on 4 September as a bank holiday in the territory.

The WHOIS++ protocol is a distributed directory system, originally designed to provide a "white pages" search mechanism to find humans, but which could actually be used for arbitrary information retrieval tasks. It was developed in the early 1990s by BUNYIP Information Systems and is documented in the IETF.

WHOIS++ was devised as an extension to the pre-existing WHOIS system. WHOIS was an early networked directory service, originally maintained by SRI International for the Defense Data Network. The WHOIS protocol is still widely used to allow domain ownership records in the Internet to be easily queried.

WHOIS++ attempted to address some of the short comings in the original WHOIS protocol that had become apparent over the years. It supported multiple languages and character sets to help with I18N issues, had a more advanced query syntax, and the ability to generate "forward knowledge" in the form of 'centroid' data structures that could be used to route queries from one server to another. The protocol was designed to be backward compatible with the older WHOIS standard, so that WHOIS++ clients could still extract meaningful information from the already deployed WHOIS servers.

Whilst WHOIS++ as a white pages directory service never really took off compared to competitors such as X.500, it did gain a notable amount of use in the United Kingdom as the underlying search and retrieval protocol of a number of subject based gateways funded as part of the Jisc Electronic library programme. This was achieved using software called ROADS that provided WHOIS++ base and index servers and CGI based web interfaces to WHOIS++ clients. The use of centroids to provide forward knowledge and query routing allowed a subject gateway to not only provide resources to academic users from their own database but also point them at other JISC funded subject gateways that might have useful information.

The WHOIS++ protocol is now designated by the IETF as a historic protocol and is no longer deployed in new systems or developed.
