The Pearl High School shooting was a school shooting that took place on October 1, 1997, at Pearl High School in Pearl, Mississippi in Greater Jackson. The gunman, 16-year-old Luke Woodham (born February 5, 1981), killed two students and injured seven others at his high school. Before the shooting at Pearl High School began, Woodham stabbed and bludgeoned his mother to death in her home.

On 22 July 2016, a shooting occurred in the vicinity of the Olympia shopping mall in the Moosach district of Munich, Germany. Ten people, including the perpetrator, were killed and 36 others were injured. The shooting took place at a McDonald's restaurant near the shopping mall, in front of a Saturn electronics store nearby, and in the mall itself. The gunman, later identified as 18-year-old David Sonboly, died nearby from a self-inflicted gunshot wound to the head. His motive for the shooting is under investigation.

The Frontier Middle School shooting was a school shooting that occurred on February 2, 1996, at Frontier Middle School in Moses Lake, Washington, United States. The gunman, 14-year-old Barry Dale Loukaitis (born February 26, 1981), killed his algebra teacher and two students, and held his classmates hostage for over an hour before a gym coach subdued Loukaitis.

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.

Viet Nguyen (, February 25, 1981 – October 6, 2007) and Duc Nguyen (, born February 25, 1981) were a pair of conjoined twins born in Vietnam and surgically separated in 1988. Viet died in 2007 of natural causes.

Viet and Duc were born on February 25, 1981, in Kon Tum Province, Tây Nguyên, Vietnam. Viet was the elder and Duc was the younger of the two brothers. Their relatives claim that "the reason they became conjoined twins is the influence of Agent Orange that the U.S. military used as a defoliant during the Vietnam War". His mother was farming in the area doused with Agent Orange a year after the Vietnam War had ended. She also drank water from a well in that area. After that, Viet and Duc were born. On October 4, 1988, Viet and Duc were separated in the hospital in Ho Chi Minh City with the help of the Japanese Red Cross after Viet went into a coma.

Duc first entered junior high school, then dropped out and learned computer programming in a school. Now, he works at a hospital in Ho Chi Minh City. On December 16, 2006, he married Nguyen Thanh Tuyen in Ho Chi Minh City.

Viet's health problems continued after the separation, and he died due to liver failure and pneumonia on October 6, 2007, at the age of 26.

The Tanganyika laughter epidemic of 1962 was an outbreak of mass hysteriaor mass psychogenic illness (MPI)rumored to have occurred in or near the village of Kashasha on the western coast of Lake Victoria in the modern nation of Tanzania (formerly Tanganyika) near the border of Uganda.

The laughter epidemic began on January 30, 1962, at a mission-run boarding school for girls in Kashasha. The laughter started with three girls and spread haphazardly throughout the school, affecting 95 of the 159 pupils, aged 12–18. Symptoms lasted from a few hours to 16 days in those affected. The teaching staff were not affected but reported that students were unable to concentrate on their lessons. The school was forced to close down on March 18, 1962.

After the school was closed and the students were sent home, the epidemic spread to Nshamba, a village that was home to several of the girls. In April and May, 217 people had laughing attacks in the village, most of them being school children and young adults. The Kashasha school was reopened on May 21, only to be closed again at the end of June. In June, the laughing epidemic spread to Ramashenye girls’ middle school, near Bukoba, affecting 48 girls.

The school from which the epidemic sprang was sued; the children and parents transmitted it to the surrounding area. Other schools, Kashasha itself, and another village, comprising thousands of people, were all affected to some degree. Six to eighteen months after it started, the phenomenon died off. The following symptoms were reported on an equally massive scale as the reports of the laughter itself: pain, fainting, flatulence, respiratory problems, rashes, attacks of crying, and random screaming. In total 14 schools were shut down and 1000 people were affected.

Islamophobia in the United States can be described as the unvalidated, highly speculative, affective distrust and hostility towards Muslims, Islam, and those perceived as following the religion and or appear as members of the religion and its associative groups. This social aversion and bias is facilitated and perpetuated by violent and uncivilized stereotypes portrayed in various forms of American media networks and political platforms that result in the marginalization, discrimination, and exclusion of the Muslims and Muslim perceived individuals. Media and politicians capitalize on public fear and distrust of Muslims through laws that specifically target Muslims, while the media emphasizes Muslim religious extremism in association with violent activity.

Advocacy groups like Center for American Progress explain that this social phenomenon is not new, but rather, has increased it’s presence in American social and political discourse over the past ten to fifteen years. They cite that several organizations donate large amounts of money to create the “Islamophobia megaphone”. CAP defines the megaphone analogy as “a tight network of anti- Muslim, anti- Islam foundations, misinformation experts, validators, grass root organizations, religious rights groups and their allies in the media and in politics” who work together to misrepresent Islam and Muslims in the United States. As a result of this network, Islam is now one of the most stigmatized religions, with only 37 percent of Americans having a favorable opinion of Islam, according to a 2010 ABC News/ Washington Post poll. This biased perception of Islam and Muslims manifests itself into the discrimination of racially perceived Muslims in the law and media, and is conceptually reinforced by the Islamophobia Network.

Islamophobia in Canada refers to set of discourses, behaviours and structures which express feelings of anxiety, fear, hostility and rejection towards Islam and/or Muslims in Canada.

Particularly since the September 11, 2001, attacks in the United States, a variety of surveys and polls as well as reported incidents have consistently given credence to the existence of Islamophobia in Canada.

Islamophobia has manifested itself as vandalism of mosques, and physical assaults on Muslims, including violence against Muslim women wearing the hijab or niqab. In January 2017, six Muslims were killed in a shooting at a Quebec city mosque. The number of Islamophobic incidents have significantly increased in the last two years. Islamophobia has been condemned by Canadian governments on the federal, provincial and municipal level.

The Canadian media have played a mixed role in their coverage of Islamophobia, and have been described as having perpetuated it and/or countered it for Canadian audiences. Canada’s public education system has also been scrutinized for its role as the site of Islamophobic incidents and of the development of Islamophobic attitudes in youth.

Abigail Loraine "Abby" Hensel and Brittany Lee Hensel (born March 7, 1990) are American dicephalic parapagus twins; in other words, they are conjoined twins, each of whom has a separate head, but whose bodies are joined.

They are highly symmetric for conjoined twins, giving the appearance of having a single body without marked variation from normal proportions. In fact, several vital organs are doubled; each twin has a separate heart, stomach, spine, pair of lungs, and spinal cord.

Each twin controls her half of their body, operating one arm and one leg. As infants, the initial learning of physical processes that required bodily coordination, such as clapping, crawling, and walking, required the cooperation of both twins.

While they can eat and write separately and simultaneously, activities such as running and swimming require them to coordinate and alternate their actions symmetrically. Other activities as diverse as brushing hair and driving a car require each twin to perform separate actions that coordinate with the other's.

Due to the curiosity that their condition generated, the twins' progress as they were growing up was covered in a number of popular media, including "Life" magazine and "The Oprah Winfrey Show". At the age of 16, they gave an interview on The Learning Channel on December 17, 2006, in which they discussed aspects of their daily lives and plans for the future. They starred in their own reality series, "Abby & Brittany", on TLC in 2012.

The twins were born in Carver County, Minnesota, to Patty, a registered nurse, and Mike Hensel, a carpenter and landscaper. They have a younger brother and sister. They were raised in New Germany, Minnesota, attended Mayer Lutheran High School in Mayer, and graduated from Bethel University in St. Paul in 2012.

At 17:52 CEST (15:52 UTC), a gunman opened fire at a McDonald's west of the Olympia shopping mall in the Moosach district of Munich, Germany. Despite initial reports of multiple attack sites, police could not confirm attacks in any other locations besides the shopping area.

Electric shock is also used as a medical therapy, under carefully controlled conditions:

- Electroconvulsive therapy or ECT is a psychiatric therapy for mental illness. The objective of the therapy is to induce a seizure for therapeutic effect. There is no conscious sensation of the electric shock because of the anesthesia used beforehand. Convulsive therapy was introduced in 1934 by Hungarian neuropsychiatrist Ladislas J. Meduna who, believing mistakenly that schizophrenia and epilepsy were antagonistic disorders, induced seizures first with camphor and then metrazol (cardiazol). The first patient was treated by Lucio Bini and Ugo Cerlettiin. ECT is generally administered three times a week for about 8-12 treatments.

- As a surgical tool for cutting or coagulation. An "Electrosurgical Unit" (or ESU) uses high currents (e.g. 10 amperes) at high frequency (e.g. 500 kHz) with various schemes of amplitude modulation to achieve the desired result - cut or coagulate - or both. These devices are safe when used correctly.

- As a treatment for fibrillation or irregular heart rhythms: see defibrillator and cardioversion.

- As a method of pain relief: see Transcutaneous Electrical Nerve Stimulator (more commonly referred to as a TENS unit).

- As an aversive punishment for conditioning of developmentally delayed individuals with severe behavioral problems. This controversial skin-shock method is employed only at the Judge Rotenberg Educational Center, a special needs school in Massachusetts.

- As a treatment for Hyperhidrosis with the device called iontophoresis

- As part of electrodiagnosis diagnostic tests including nerve conduction studies and electromyography.

- For genetic engineering and gene delivery using a non-viral vector system electroporation

Queen bee syndrome was first defined by G.L. Staines, T.E. Jayaratne, and C. Tavris in 1973. It describes a woman in a position of authority who views or treats subordinates more critically if they are female. This phenomenon has been documented by several studies. In another study, scientists from the University of Toronto speculated that the queen bee syndrome may be the reason that women find it more stressful to work for women managers; no difference was found in stress levels for male workers. An alternate, though closely related, definition describes a queen bee as one who has succeeded in her career, but refuses to help other women do the same.

Middle school and high school seems to be the place in which the queen bee syndrome is born. Much research has been devoted to the investigation of the interactions of adolescent girls. This is where vicious bullying of teen girls shows up, often with the operations spearheaded by one individual, who has as of late been dubbed the "queen bee." In recent years, research has shown that adolescent girls form (often small) groups called cliques, which are often created based on a shared characteristic or quality of the members such as attractiveness or popularity. Association with such a group is often wanted by those who are part of the larger, all encompassing group, such as a class or school. It is the association with these groups that brings an individual similar treatment.

The term feeble-minded was used from the late nineteenth century in Europe, the United States and Australasia for disorders later referred to as illnesses or deficiencies of the mind.

At the time, "mental deficiency" encompassed all degrees of educational and social deficiency. Within the concept of mental deficiency, researchers established a hierarchy, ranging from idiocy, at the most severe end of the scale; to imbecility, at the median point; and to feeble-mindedness at the highest end of functioning. The latter was conceived of as a form of high-grade mental deficiency.

The development of the ranking system of mental deficiency has been attributed to Sir Charles Trevelyan in 1876, and was associated with the rise of eugenics. The term and hierarchy had been used in that sense at least ten years previously. "Wild card" terms outside the established hierarchy such as "idiot savant", may have been used as connotations for varying degrees of autism.

Mild electric shocks are also used for entertainment, especially as a practical joke for example in such devices as a shocking pen or a shocking gum. However devices such as a joy buzzer and most other machines in amusement parks today only use vibration that feels somewhat like an electric shock to someone not expecting it.

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.

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.

Obesity in China is a major health concern according to the WHO, with overall rates of obesity below 5% in the country, but greater than 20% in some cities. This is a dramatic change from times when China experienced famine as a result from ineffective agriculturalization plans such as the Great Leap Forward.

Currently, obesity in China is mostly confined to the cities where fast food culture and globalization have taken over, in comparison to poorer rural areas. Despite this concentration of obesity, the sheer size of China's population means that over one fifth of all one billion obese people in the world come from China.

Islamophobia is a neologism formed by combining "Islam" and the suffix "-phobia", implying the basic meaning of "Islamophobia" to be "fear of Islam" or "aversion to Islam". The definition of the term can vary. The Ontario Human Rights Commission gives an example definition of Islamophobia: "stereotypes, bias or acts of hostility towards individual Muslims or followers of Islam in general." The Oxford English Dictionary defines Islamophobia as "intense dislike or fear of Islam, esp. as a political force; hostility or prejudice towards Muslims". The Oxford dictionary pinpoints the term's first known usage in English to 1923, although the historical origin of the term is contested. This definition reflects the view that hostility toward Islam as a religion can potentially overlap with the more xenophobic and racialized forms of hostility toward Muslims as a community or people.

In 1996, the Runnymede Trust in the United Kingdom established the Commission on British Muslims and Islamophobia. In "Islamophobia: A Challenge for Us All", a 1997 report of the Commission's findings, Islamophobia was defined as "an outlook or world-view involving an unfounded dread and dislike of Muslims, which results in practices of exclusion and discrimination." "Islamophobia: A Challenge for Us All" outlined the following eight recurring views of Islam that constitute Islamophobia:

After analyzing the nuances in many definitions of Islamophobia, Robin Richardson, a former director of the Runnymede Trust and the editor of "Islamophobia: A Challenge for Us All", concludes that the term can be acceptably defined as "a shorthand term referring to a multifaceted mix of discourse, behaviour and structures which express and perpetuate feelings of anxiety, fear, hostility and rejection towards Muslims, particularly but not only in countries where people of Muslim heritage live as minorities."

Transphobia is a range of negative attitudes, feelings or actions toward transgender or transsexual people, or toward transsexuality. Transphobia can be emotional disgust, fear, violence, anger or discomfort felt or expressed towards people who do not conform to society's gender expectations. It is often expressed alongside homophobic views and hence is often considered an aspect of homophobia. Transphobia is a type of prejudice and discrimination similar to racism and sexism, and transgender people of color are often subjected to all three forms of discrimination at once.

Child victims of transphobia experience harassment, school bullying, and violence in school, foster care, and social programs. Adult victims experience public ridicule, harassment including misgendering, taunts, threats of violence, robbery, and false arrest; many feel unsafe in public. A high percentage report being victims of sexual violence. Some are refused healthcare or suffer workplace discrimination, including being fired for being transgender, or feel under siege by conservative political or religious groups who oppose laws to protect them. There is even discrimination from some people within the movement for the rights of gender and sexual minorities.

Besides the increased risk of violence and other threats, the stress created by transphobia can cause negative emotional consequences which may lead to substance abuse, running away from home (in minors), and a higher rate of suicide.

In the Western world, there have been gradual changes towards the establishment of policies of non-discrimination and equal opportunity. The trend is also taking shape in developing nations. In addition, campaigns regarding the LGBT community are being spread around the world to improve acceptance; the "Stop the Stigma" campaign by the UN is one such development.

Uniform fetishism is a sexual fetishism where an individual is sexually aroused by uniforms.

The earliest recorded use of the term in the English language dates from 1534, when it appears in one of the first English translations of the New Testament. A biblical injunction to "Comforte the feble mynded" is included in 1 Thessalonians 5:14.

A London "Times" editorial of November 1834 describes the long-serving former Prime Minister Lord Liverpool as a "feeble-minded pedant of office".

The incident began in the morning of October 1, 1997, when Luke Woodham fatally stabbed and bludgeoned his mother, Mary Ann Woodham, as she prepared for a morning jog. At his trial, Woodham claimed that he could not remember killing his mother. Mary Ann Woodham died 20 minutes later from blood loss.

Woodham then drove his mother's Toyota Tercel to Pearl High School. Wearing a trench coat to hide his rifle when he entered the school, Woodham fatally shot Lydia Kaye Dew and Christina Menefee, his former girlfriend, then went on to wound seven others.

The school's assistant principal, Joel Myrick, retrieved a .45 caliber semi-automatic pistol from his truck and, spotting Woodham attempting to flee the parking lot after the shooting, shouted for him to stop. Realizing what Woodham was doing, another student used his own vehicle to block Woodham's path, at which point Woodham attempted to get around the obstruction by driving his mother's car onto a grass verge, only to end up getting stuck in the grass. Seizing his opportunity, Myrick ordered Woodham out of the car at gunpoint and detained him until police arrived at the scene.

Minutes before he started the shooting, Woodham had given the following message to his friend Justin Sledge:

During the subsequent investigation, Woodham's journal was examined by police. In it, he detailed how he and a friend had tortured his dog Sparkle to death, several months prior to the shooting:
