There have been allegations of doping in the Tour de France since the race began in 1903. Early Tour riders consumed alcohol and used ether, among other substances, as a means of dulling the pain of competing in endurance cycling. Riders began using substances as a means of increasing performance rather than dulling the senses, and organizing bodies such as the "Tour" and the International Cycling Union (UCI), as well as government bodies, enacted policies to combat the practice.

Use of performance-enhancing drugs in cycling predates the Tour de France. Cycling, having been from the start a sport of extremes, whether of speed by being paced by tandems, motorcycles and even cars, or of distance, the suffering involved encouraged the means to alleviate it. Not until after World War II were sporting or even particularly health issues raised. Those came shortly before the death of Tom Simpson in the Tour de France of 1967. Max Novich referred to the Tour de France in a 1973 issue of "New York State Journal of Medicine" as "a cycling nightmare". In the eyes of a 1998 German observer:

The Hungerford massacre was a series of random shootings in Hungerford, England, United Kingdom, on 19 August 1987, when Michael Robert Ryan, an unemployed antique dealer and handyman, fatally shot 16 people, including a police officer, before taking his own life. The shootings, committed using a handgun and two semi-automatic rifles, occurred at several locations, including a school he had once attended. 15 other people were also shot but survived. No firm motive for the killings has ever been established, although one psychologist has theorised Ryan's motive for the massacre had been a form of "anger and contempt for the ordinary life" around him, which he himself was not a tangible part of.

A report was commissioned by Home Secretary Douglas Hurd. The Firearms (Amendment) Act 1988 was passed in the wake of the massacre, which bans the ownership of semi-automatic centre-fire rifles and restricts the use of shotguns with a capacity of more than three cartridges. The shootings remain one of the deadliest firearms incidents in British history.

Anti-Chinese sentiment in Japan has been present since the Tokugawa period. Anti-Chinese sentiments in Japan have been on a sharp rise since 2002. According to Pew Global Attitude Project (2008), unfavorable view of China was 84%, unfavorable view of Chinese people was 73%.

Anti-Chinese sentiment in the United States has existed since the late 18th century. Its origins have been traced to the American merchants, missionaries, and diplomats who sent home from China "relentlessly negative" reports of the people they encountered there. These attitudes were transmitted to Americans who never left North America, triggering talk of the Yellow Peril, and continued through the Cold War during McCarthyism. Modern anti-Chinese sentiment is the result of China's rise as a major world power. Anti-Chinese sentiment or sinophobia is a broad opposition or hostility to the people, policies, culture, or politics of China.

Anti-Arabism, Anti-Arab sentiment or Arabophobia is opposition to, or dislike, fear, hatred, and advocacy of genocide of Arab people.

Historically, anti-Arab prejudice has been suggested by such events as the reconquest of the Iberian Peninsula, the condemnation of Arabs in Spain by the Spanish Inquisition, the Zanzibar Revolution in 1964, and the 2005 Cronulla riots in Australia. In the current era, racial prejudice against Arabs is apparent in many countries including Iran, Poland, France, Australia, Israel, and the United States (including Hollywood). Various advocacy organizations have been formed to protect the civil rights of Arab citizens in the United States, such as the American-Arab Anti-Discrimination Committee (ADC) and the Council on American-Islamic Relations (CAIR).

Anti-Chinese sentiment, Sinophobia (from Late Latin "Sinae" "China" and Greek φόβος, "phobos", "fear"), or Chinophobia is a sentiment against China, its people, overseas Chinese, or Chinese culture. It often targets Chinese minorities living outside of China and is complicated by the dilemma of immigration, development of national identity in neighbouring countries, disparity of wealth, the fall of the past central tribute system and majority-minority relations. Its opposite is Sinophilia. Factors contributing to sinophobia include disapproval of the Chinese government, historical grievances, fear of economic competition, and racism. Sinophobia also stems from older ethnic tensions, such as those related to Japanese nationalism, Korean nationalism, Indian nationalism and Vietnamese nationalism.

The distinction between Hua () and Yi (), also known as Sino–barbarian dichotomy, is an ancient Chinese concept that differentiated a culturally defined "China" (called Hua, Huaxia 華夏, or Xia 夏) from cultural or ethnic outsiders (Yi "barbarians"). Although Yi is often translated as "barbarian", other translations of this term in English include "foreigners",

"ordinary others" "wild tribes", and "uncivilized tribes."

The Hua–Yi distinction asserted Chinese superiority, but implied that outsiders could become "Hua" by adopting Chinese values and customs.

A specific fear of clowns has sometimes been discussed in terms of a specific phobia. The term "" is a neologism coined in the context of informal ""-phobia" lists".

The term is not listed in the World Health Organisation's ICD-10 nor in the American Psychiatric Association's DSM-5 categorization of disorders.

Media, marketers, politicians, youth workers and researchers have been implicated in perpetuating the fear of youth. Since young people in developed countries are expected to stay out of the workforce, any role for them outside that of consumer is potentially threatening to adults. Selling safety to parents and teachers has also been a driving force, as home security systems, cellphones, and computer surveillance usage is marketed to parents; and x-ray machines, metal detectors and closed-circuit television are increasingly sold to schools on the premise that young people are not to be trusted. These steps are in spite of the fact that experience consistently shows that monitoring youth does little to prevent violence or tragedy: the Columbine High School massacre occurred in a building with video surveillance and in-building police.

The very creation of the terms youth, adolescence and teenager have all been attributed to the fear of youth. As the western world became more industrialized, young people were increasingly driven from the workforce, including involuntary and voluntary positions, and into increasingly total institutions where they lost personal autonomy in favor of social control. Government policies outside of schools have been implicated as well, as over the last forty years curfews, anti-loitering and anti-cruising laws, and other legislation apparently targeted at teenagers have taken hold across the country. Courts have increasingly ruled against youth rights, as well. Before the 1940s "teenagers" were not listed in newspaper headlines, because as a group they did not exist. The impact of youth since World War II on western society has been immense, largely driven by marketing that proponents them as the "Other". In turn, youth are caused to behave in ways that appear different from adults. This has led to the phenomenon of youth, and in turn has created a perpetuated fear of them.

Ephebiphobia is the fear of youth. First coined as the "fear or loathing of teenagers", today the phenomenon is recognized as the "inaccurate, exaggerated and sensational characterization of young people" in a range of settings around the world. Studies of the fear of youth occur in sociology and youth studies.

14 of the 25 most recent winners (56%) have either failed tests or have confessed to have used doping. Together with those who failed tests but never sanctioned, 68% of the winners evidently used doping as detailed in the table below.

In the "Space To Care" study aimed at improving hospital design for children, researchers from the University of Sheffield polled 250 children regarding their opinions on décor for a forthcoming hospital redesign; all 250 children, whose ages ranged between four and sixteen, reported that they disliked clowns as part of hospital décor. Many of them, including some older children, stated in the poll that they, in fact, actively feared clowns. In other studies playing with therapeutic clowns reduced anxiety in children and improved healing in children with respiratory illness.

Arabs are people whose native language is Arabic. People of Arabic origin, in particular native English and French speakers of Arab ancestry in Europe and the Americas, often identify themselves as Arabs. Due to widespread practice of Islam among Arab populations, Anti-Arabism is commonly confused with Islamophobia.

There are prominent Arab non-Muslim minorities in the Arab world. These minorities include the Arab Christians in Lebanon, Syria, Palestine, Jordan, Egypt, Iraq and Kuwait, among other Arab countries. There are also sizable minorities of Arab Jews, Druze, and nonreligious. Most Arabs are Caucasian. Exceptions are Mauritanian, Sudanese, Eritrean, Somali, and Comoran Arabs.

Michael Robert Ryan was an unemployed labourer and antiques dealer. He was born at Savernake Hospital in Marlborough, Wiltshire, located near Hungerford, Berkshire, on 18 May 1960. His father, Alfred Henry Ryan, was 55 years old when Michael was born. Alfred died in Swindon in May 1985 at the age of 80. At the time of the shooting, Ryan lived with his mother, Dorothy, a dinner lady at the local primary school. He had no siblings. There was extensive press comment on this, suggesting the relationship was "unhealthy" and that Ryan was "spoiled" by his mother. A "Guardian" headline described Ryan as a "mummy's boy". Ryan was a bachelor and had no children.

Ryan's true motives may never be known as he killed himself and his mother, the only other person who knew him well. Dr John Hamilton of Broadmoor Hospital and Dr Jim Higgins, a consultant forensic psychiatrist for Mersey Regional Health Authority, both thought he was schizophrenic and psychotic. Hamilton stated "Ryan was most likely to be suffering from acute schizophrenia. He might have had a reason for doing what he did, but it was likely to be bizarre and peculiar to him." The local vicar, the Reverend David Salt, said on the first anniversary of the massacre, "No one has ever explained why Michael Ryan did what he did. And that's because, in my opinion, it is not something that can be explained." Ryan's body was cremated at the Reading Crematorium on 3 September 1987, 15 days after he took his own life.

Concerns over legitimacy were not limited to the Song alone: states rose up again in the Yuan dynasty, as its rulers were non-Han Chinese. However, the Yuan dynasty adopted a different approach to quelling the conflict. The Yuan asserted that the Song, Liao and Jin were all legitimate; therefore all three dynasties were given their own history, as recognition of their legitimacy.

Despite this, the Yuan racially segregated their people; dividing society into four categories:

- Mongols (蒙古): the ruling group and hence, the most important

- Semu (色目; "assorted categories"): a term for non-Chinese and non-Mongol foreigners who occupied the second slate;

- Han (漢人): a term for the Han Chinese, Jurchens, and Khitan under the rule of the Jin dynasty;

- Southerner (南人): a term for Han Chinese under the rule of the Song dynasty.

In addition, the Yuan also divided society into 10 castes, based on "desirability":

- High officials (大官)

- Minor officials (小官)

- Buddhist monks (釋)

- Daoist priests (道)

- Physicians (医)

- Peasants (農)

- Hunters (獵)

- Courtesans (妓)

- Confucian scholars (儒)

- Beggars (丐)

The Yuan rulers were Mongols and were viewed as barbaric and humiliating for the Han Chinese, although they did not last long in China (from 1271 to 1368).

A false memory is the psychological phenomenon where a person recalls something that did not happen. False memory is often considered in legal cases regarding childhood sexual abuse. This phenomenon was initially investigated by psychological pioneers Pierre Janet and Sigmund Freud. Freud wrote "The Aetiology of Hysteria", where he discussed repressed memories of childhood sexual trauma in their relation to hysteria. Elizabeth Loftus has, since her debuting research project in 1974, been a lead researcher in memory recovery and false memories. False memory syndrome recognizes false memory as a prevalent part of one's life in which it affects the person's mentality and day-to-day life. False memory syndrome differs from false memory in that the syndrome is heavily influential in the orientation of a person's life, while false memory can occur without this significant effect. The syndrome takes effect because the person believes the influential memory to be true. However, its research is controversial and the syndrome is excluded from identification as a mental disorder and, therefore, is also excluded from the "Diagnostic and Statistical Manual of Mental Disorders". False memory is an important part of psychological research because of the ties it has to a large number of mental disorders, such as PTSD.

According to a recent Pew Research Center survey of six African countries, Ghana, Kenya, Nigeria, Senegal, South Africa, and Uganda had higher disapproval towards China compared to previous years while they had higher positive view for the United States.

As part of the Chinese exclusion policy of NASA, many American space researchers were prohibited from working with Chinese citizens affiliated with a Chinese state enterprise or entity. In April 2011, the 112th United States Congress banned NASA from using its funds to host Chinese visitors at NASA facilities. Earlier in 2010, Rep. John Culberson (R-TX) had urged President Barack Obama not to allow further contact between NASA and the China National Space Administration (CNSA).

If a child experienced abuse, it is not typical for them to disclose the details of the event when confronted in an open-ended manner. Trying to indirectly prompt a memory recall can lead to the conflict of source attribution, as if repeatedly questioned the child may try to recall a memory to satisfy a question. The stress being put on the child can make recovering an accurate memory more difficult. Some people hypothesise that as the child continuously attempts to remember a memory, they are building a larger file of sources that the memory could be derived from, potentially including sources other than genuine memories. Children that have never been abused that undergo similar response-eliciting techniques can disclose events that never occurred. If one concludes that the child's recalled memory is false, it is a type I error. Assuming the child did not recall an existing memory, it is a type II error.

One of children's most notable setbacks in memory recall is source misattribution. Source misattribution is the flaw in deciphering between potential origins of a memory. The source could come from an actual occurring perception, or it can come from an induced and imagined event. Younger children, preschoolers in particular, find it more difficult to discriminate between the two. Lindsay & Johnson (1987) concluded that even children approaching adolescence struggle with this, as well as recalling an existent memory as a witness. Children are significantly more likely to confuse a source between being invented or existent.

Following the end of the World War II, openly Sinophobic sentiments were stifled and became taboo in the mainstream media, even though Japan and the People's Republic of China took opposite sides in the Cold War. Except in a handful of cases, such as the Japanese name for "South China Sea" and an alternative term for ramen, use of the word "Shina" (; China) all but disappeared.

There was little contact between Japan and the People's Republic of China in the ensuing decades. There was little discussion of China until the relationship between the countries was normalised in 1972, when there was a surge of interest in Japan about its neighbour. China renounced reparations for the Second World War, partly to avoid appearing less generous than Taiwan—which had earlier done the same—and to strengthen its position against the Soviet Union. The response was considerable gratitude and goodwill in Japan. Sinophobia was confined to the context of fear of communism. Public animosity toward the People's Republic of China was minimal compared to the public animosity held against the Soviet Union, and a friendly mood prevailed. Improvements were also seen in social attitudes toward ethnic Chinese residents of Japan, along with other minorities such as Zainichi Koreans and Ainu people.

However, since 2000, Japan has seen a gradual resurgence of anti-Chinese sentiments. The xenophobic sentiments are coupled with the effects of an increasingly tense political relationship between Japan and the People's Republic of China. Many Japanese believe that China is using the issue of the countries' checkered history, such as the Japanese history textbook controversies and official visits to the Yasukuni Shrine, both as a diplomatic card and to make Japan a scapegoat in domestic politics. The anti-Japanese riots in the spring of 2005 caused more fear of China within the Japanese public. Anti-Chinese sentiments in Japan have been on a sharp rise since 2002. According to Pew Global Attitude Project (2008), unfavorable view of China was 84%, unfavorable view of Chinese people was 73%.

CML accounts for 8% of all leukaemias in the UK, and around 680 people were diagnosed with the disease in 2011.

The American Cancer Society estimates that in 2014, about 5,980 new cases of chronic myelogenous leukemia were diagnosed, and about 810 people died of the disease. This means that a little over 10% of all newly diagnosed leukemia cases will be chronic myelogenous leukemia. The average risk of a person getting this disease is 1 in 588. The disease is more common in men than women, and more common in whites than African-Americans. The average age at diagnosis is 64 years, and this disease is rarely seen in children.
