77-833: Operation Fiery Vigil was the emergency evacuation of all non-essential military and U.S. Department of Defense civilian personnel and their dependents from Clark Air Base and U.S. Naval Base Subic Bay during the June 1991 eruption of Mount Pinatubo in the Republic of the Philippines. This Non-combatant evacuation operation transferred roughly 20,000 people from Clark Air Base and U.S. Naval Base Subic Bay back to contiguous United States by way of Cebu , Philippines. Major General William A. Studer , Commander, Thirteenth Air Force , served as Commander Joint Task Force - Fiery Vigil. The 1991 Ultra-Plinian eruption of Mount Pinatubo

154-751: A Volcanic Explosivity Index of 6. By contrast, roughly four cubic kilometres (0.96 cu mi) of material was ejected in the 1980 eruption of Mount St. Helens ; this corresponds to a VEI of 5. Very few of the estimated 20,000 who left the base ever returned. The vast majority were evacuated to Andersen Air Force Base , Guam and processed for return to the continental United States. This figure includes approximately 5,000 who were evacuated to Cebu City on USS  Midway , USS  Abraham Lincoln , USS  Long Beach , USS  Peleliu , USS  Arkansas , USS Gary , USS  San Bernardino , USS  Rodney M. Davis , USS  Ingraham , USS Lake Champlain , and sixteen other U.S. Navy ships of

231-661: A building due to a storm or fire to the large-scale evacuation of a city because of a flood, bombardment or approaching weather system , especially a tropical cyclone . In situations involving hazardous materials or possible contamination , evacuees may be decontaminated prior to being transported out of the contaminated area. Evacuation planning is an important aspect to mitigat the impact of disasters on humans. Today there many evacuation models to simulate this process for small-scale and large-scale situations. Evacuations may be carried out before, during, or after disasters such as: Emergency evacuation plans are developed to ensure

308-407: A coastal town many times without the town ever actually experiencing the brunt of a storm. If evacuation orders are given too early, the hurricane can change course and leave the evacuated area unscathed. People may think they have weathered hurricanes before, when in reality the hurricane didn't hit them directly, giving them false confidence. Those who have lived on the coast for ten or more years are

385-429: A disability can impact people's identities. Which style of language used varies between different countries, groups and individuals. Identity-first language describes the person as "disabled". Some people prefer this and argue that this fits the social model of disability better than people-first language, as it emphasizes that the person is disabled not by their body, but by a world that does not accommodate them. This

462-561: A disability community—such as with art, social media, and sports. Contemporary understandings of disability derive from concepts that arose during the scientific Enlightenment in the west; prior to the Enlightenment, physical differences were viewed through a different lens. There is evidence of humans during prehistory that looked after people with disabilities. At the Windover Archeological Site , one of

539-628: A disability". This style is reflected in major legislation on disability rights, including the Americans with Disabilities Act and the UN Convention on the Rights of Persons with Disabilities . "Cerebral Palsy: A Guide for Care" at the University of Delaware describes people-first language: The American Psychological Association style guide states that, when identifying a person with

616-426: A disability, the person's name or pronoun should come first, and descriptions of the disability should be used so that the disability is identified, but is not modifying the person. Acceptable examples included "a woman with Down syndrome " or "a man who has schizophrenia ". It also states that a person's adaptive equipment should be described functionally as something that assists a person, not as something that limits

693-411: A distinction between assembly and embarkation (to boats or rafts) is made. These are separate from each other. The decision whether to enter the boats or rafts is thus usually made after assembly is completed. The strategy of individuals in evacuating buildings has been investigate in many disaster in the last 50 years. The complexity of the building, the pre-movement decisions and the movement ability of

770-409: A faster evacuation time: Mostly by localizing the fire sources, analysing the fire spreading inside the building or finding people that are trapped inside the building. Some buildings can have a monitoring interface that provides all these kind of information to evacuate in the best way possible. The evacuation of districts is part of disaster management . Many of the largest evacuations have been in

847-405: A feature that creates an impairment, restriction, or limitation from reaching the social definition of health, the individual is labeled as disabled. Under this idea, disability is not defined by the physical features of the body but by a deviance from the social convention of health. The social construction of disability would argue that the medical model of disability 's view that a disability

924-424: A given society. Disabilities may be cognitive , developmental , intellectual , mental , physical , sensory , or a combination of multiple factors. Disabilities can be present from birth or can be acquired during a person's lifetime. Historically, disabilities have only been recognized based on a narrow set of criteria—however, disabilities are not binary and can be present in unique characteristics depending on

1001-400: A matter of the full integration of individuals into society . In this model, disability is not an attribute of an individual, but rather a complex collection of conditions, created by the social environment. The management of the problem requires social action and it is the collective responsibility of society to create a society in which limitations for disabled people are minimal. Disability

1078-506: A negative connotation that they are considered to be slurs. A current point of contention is whether it is appropriate to use person-first language (i.e. a person who is disabled) or identity-first language (i.e. a disabled person) when referring to disability and an individual. Due to the marginalization of disabled people, there have been several activist causes that push for equitable treatment and access in society. Disability activists have fought to receive equal and equitable rights under

1155-433: A person's capability to perform the activities of daily life. As Marta Russell and Ravi Malhotra argue, "The ' medicalization ' of disablement and the tools of classification clearly played an important role in establishing divisions between the 'disabled' and the 'able-bodied. ' " This positions disability as a problem to be solved via medical intervention, which hinders our understanding about what disability can mean. For

1232-413: A person's efforts to go to school, work, socialize, and more. Some examples of invisible disabilities include intellectual disabilities , autism spectrum disorder , attention deficit hyperactivity disorder , fibromyalgia , mental disorders , asthma , epilepsy , allergies , migraines , arthritis , and chronic fatigue syndrome . Employment discrimination is reported to play a significant part in

1309-614: A person, for example, "a woman who uses a wheelchair" rather than "a woman in/confined to a wheelchair". People-first terminology is used in the UK in the form "people with impairments" (such as "people with visual impairments"). However, in the UK, identity-first language is generally preferred over people-first language. The use of people-first terminology has given rise to the use of the acronym PWD to refer to person(s) (or people) with disabilities (or disability). However other individuals and groups prefer identity-first language to emphasize how

1386-492: A political construction is also widely used by international organizations of disabled people, such as Disabled Peoples' International . Using the identity-first language also parallels how people talk about other aspects of identity and diversity. For example: In the autism community, many self-advocates and their allies prefer terminology such as 'Autistic,' 'Autistic person,' or 'Autistic individual' because we understand autism as an inherent part of an individual's identity –

1463-451: A problem of the person, directly caused by disease, trauma, or other health conditions which therefore requires sustained medical care in the form of individual treatment by professionals. In the medical model, management of the disability is aimed at a "cure", or the individual's adjustment and behavioral change that would lead to an "almost-cure" or effective cure. The individual, in this case, must overcome their disability by medical care. In

1540-510: A societally-created limitation on individuals who do not have the same ability as the majority of the population. Although the medical model and social model are the most common frames for disability, there are a multitude of other models that theorize disability. There are many terms that explain aspects of disability. While some terms solely exist to describe phenomena pertaining to disability, others have been centered around stigmatizing and ostracizing those with disabilities. Some terms have such

1617-552: A society) that help overcome or remove a disability. The first recorded example of the use of a prosthesis dates to at least 1800 BC. The wheelchair dates from the 17th century. The curb cut is a related structural innovation. Other examples are standing frames , text telephones , accessible keyboards , large print , braille , and speech recognition software . Disabled people often develop adaptations which can be personal (e.g. strategies to suppress tics in public) or community (e.g. sign language in d/Deaf communities). As

1694-502: A variety of different theoretical lenses. There are two main models that attempt to explain disability in our society: the medical model and the social model . The medical model serves as a theoretical framework that considers disability as an undesirable medical condition that requires specialized treatment. Those who ascribe to the medical model tend to focus on finding the root causes of disabilities, as well as any cures—such as assistive technology. The social model centers disability as

1771-401: A wheelchair, multiple sclerosis , muscular dystrophy , obsessive–compulsive disorder (OCD), post-traumatic stress disorder (PTSD), spina bifida , and schizophrenia . This is not an exhaustive list and many injuries and medical problems cause disability. Some causes of disability, such as injuries, may resolve over time and are considered temporary disabilities . An acquired disability

1848-598: Is a container of food, clothing, water, and other supplies that can be used to sustain an individual during lag time. Lag time is the period between the actual occurrence of an emergency and when organized help becomes available, generally 72 hours, though this can vary from a few hours to several days. It may take this long for authorities to get evacuation shelters fully up and functional. During this time, evacuees may suffer fairly primitive conditions; no clean water, heat, lights, toilet facilities, or shelter. An emergency evacuation kit, or 72-hour kit, can help evacuees to endure

1925-432: Is an impairment, restriction, or limitation is wrong. Instead what is seen as a disability is just a difference in the individual from what is considered "normal" in society. People-first language is one way to talk about disability which some people prefer. Using people-first language is said to put the person before the disability. Those individuals who prefer people-first language would prefer to be called, "a person with

2002-407: Is both cultural and ideological in creation. According to the social model, equal access for someone with an impairment/disability is a human rights concern. The social model of disability has come under criticism. While recognizing the importance played by the social model in stressing the responsibility of society, scholars, including Tom Shakespeare , point out the limits of the model and urge

2079-458: Is defined as the execution of a task or action. The ICF lists nine broad domains of functioning which can be affected: In concert with disability scholars, the introduction to the ICF states that a variety of conceptual models have been proposed to understand and explain disability and functioning, which it seeks to integrate. These models include the following: The medical model views disability as

2156-439: Is especially true in the UK, where it is argued under the social model that while someone's impairment (for example, having a spinal cord injury ) is an individual property, "disability" is something created by external societal factors such as a lack of accessibility. This distinction between the individual property of impairment and the social property of disability is central to the social model . The term "disabled people" as

2233-417: Is experienced differently based on the other multi-faceted identities of the individual is one often pointed out by disabled self-advocates. The ostracization of disability from mainstream society has created the opportunity for a disability culture to emerge. While disabled activists still promote the integration of disabled people into mainstream society, several disabled-only spaces have been created to foster

2310-551: Is more information given about the degree of danger. During an evacuation, people often use the most known escape route, this is often the route through which they entered the building. Thereby, people mostly adapt the role follower in emergencies. These human reactions will determinate the strategy of individuals in evacuating buildings. The most common equipment in buildings to facilitate emergency evacuations are fire alarms , exit signs , and emergency lights . Some structures need special emergency exits or fire escapes to ensure

2387-413: Is taken into account, including alarm signals that use both aural and visual alerts, and also evacuation equipment such as sleds, pads, and chairs for non-ambulatory people. Considering the persons with a disability during an emergency evacuation is important. This is because it is crucial that every user gets out of the building or to a safe place in the building, thus also the persons with disabilities or

2464-492: Is the idea that disability is constructed by social expectations and institutions rather than biological differences. Highlighting the ways society and institutions construct disability is one of the main focuses of this idea. In the same way that race and gender are not biologically fixed, neither is disability. Around the early 1970s, sociologists, notably Eliot Friedson, began to argue that labeling theory and social deviance could be applied to disability studies. This led to

2541-403: Is the result of impairments that occur suddenly or chronically during the lifespan, as opposed to being born with the impairment. Invisible disabilities may not be obviously noticeable. The medical model focuses heavily on finding treatments, cures, or rehabilitative practices for disabled people. Assistive technology is a generic term for devices and modifications (for a person or within

2618-506: The Middle Ages , disabled people were still able to play significant roles in the rural production based economy, allowing them to make genuine contributions to daily economic life. The Industrial Revolution and the advent of capitalism made it so that people were no longer tied to the land and were then forced to find work that would pay a wage in order to survive. The wage system, in combination with industrialized production, transformed

2695-493: The World Health Organization , distinguishes between body functions (physiological or psychological, such as vision) and body structures (anatomical parts, such as the eye and related structures). Impairment in bodily structure or function is defined as involving an anomaly, defect, loss or other significant deviation from certain generally accepted population standards, which may fluctuate over time. Activity

2772-616: The personal computer has become more ubiquitous, various organizations have formed to develop software and hardware to make computers more accessible for disabled people. Some software and hardware, such as Voice Finger , Freedom Scientific 's JAWS , the Free and Open Source alternative Orca etc. have been specifically designed for disabled people while other software and hardware, such as Nuance 's Dragon NaturallySpeaking , were not developed specifically for disabled people, but can be used to increase accessibility. The LOMAK keyboard

2849-484: The 1830s of l'homme moyen – the average man. Quetelet postulated that one could take the sum of all people's attributes in a given population (such as their height or weight) and find their average and that this figure should serve as a statistical norm toward which all should aspire. This idea of the statistical norm threads through the rapid take-up of statistics gathering by Britain, the United States, and

2926-549: The Ancient Greeks may not have viewed persons with disability all that differently from more able-bodied individuals as terms describing them in their records appear to be very vague. As long as the disabled person in question could still contribute to society, the Greeks appeared to tolerate them. During the Middle Ages , madness and other conditions were thought to be caused by demons. They were also thought to be part of

3003-460: The United States, elementary schools are usually more numerous in a community than other public structures. Their locations and inherent design to accommodate bus transportation makes it an ideal evacuation point. In the United States, a person usually cannot be forced to evacuate. To facilitate voluntary compliance with mandatory evacuation orders first responders and disaster management officials have used creative techniques such as asking people for

3080-466: The Western European states during this time period, and it is tied to the rise of eugenics . Disability, as well as the concepts of abnormal, non-normal, and normalcy, came from this. The circulation of these concepts is evident in the popularity of the freak show , where showmen profited from exhibiting people who deviated from those norms. With the rise of eugenics in the latter part of

3157-562: The availability of alternative escape paths. Commercial passenger vehicles such as buses, boats, and aircraft also often have evacuation lighting and signage, and in some cases windows or extra doors that function as emergency exits. Commercial emergency aircraft evacuation is also facilitated by evacuation slides and pre-flight safety briefings. Military aircraft are often equipped with ejection seats or parachutes . Water vessels and commercial aircraft that fly over water are equipped with personal flotation devices and life rafts . Since

3234-427: The building that is reinforced to protect against specific hazards, such as fire, smoke or structural collapse. Some hazards may have safe havens on each floor, while a hazard such as a tornado, may have a single safe haven or safe room . Typically persons with limited mobility are requested to report to a safe haven for rescue by first responders. In most buildings, the safe haven will be in the stairwell. By investing

3311-573: The city was flooded and uninhabitable, some people still refused to leave their homes. The longer a person has lived in a coastal area, the less likely they are to evacuate. A hurricane's path is difficult to predict. Forecasters know about hurricanes days in advance, but their forecasts of where the storm will hit are only educated guesses. Hurricanes give a lot of warning time compared to most disasters humans experience. This allows forecasters and officials to "cry wolf," making people take evacuation orders less seriously. Hurricanes can be predicted to hit

3388-430: The creation of the social construction of disability theory. The social construction of disability is the idea that disability is constructed as the social response to a deviance from the norm. The medical industry is the creator of the ill and disabled social role. Medical professionals and institutions, who wield expertise over health, have the ability to define health and physical and mental norms. When an individual has

3465-454: The emergence of The Internet of Things technologies, new techniques are appearing, which involves new equipment. Most of them are wireless devices such as IDs scanner, beacons or backscatter system. The new techniques are for example based on a communication protocol such as Wi-Fi , Bluetooth , UWB or RFID and the use of indoor positioning system . The use of The Internet of Things technologies in small scale evacuations can result in

3542-439: The evacuation experience with dignity and a degree of comfort. The development of digital infrastructure resources opened a new research area in the design of cyber-physical systems to provide the individual with safer options during an emergency evacuation. Disability Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within

3619-468: The face of wartime military attacks. Modern large scale evacuations are usually the result of natural disasters. The largest peacetime evacuations in the United States to date occurred during Hurricane Gustav and the category-5 Hurricane Rita (2005) in a scare one month after the flood-deaths of Hurricane Katrina . Despite mandatory evacuation orders, many people did not leave New Orleans , United States , as Hurricane Katrina approached. Even after

3696-412: The field include Marta Russell , Robert McRuer , Johanna Hedva , Laura Hershey , Irving Zola , and many more. Prominent disability scholar Lennard J. Davis notes that disability studies should not be considered a niche or specialized discipline, but instead is applicable to a wide range of fields and topics. The International Classification of Functioning, Disability and Health (ICF), produced by

3773-720: The gods. In Ancient Egypt , staffs were frequently used in society. A common usage for them was for older persons with disabilities to help them walk. Provisions that enabled individuals with impaired mobility to access temples and healing sanctuaries were made in ancient Greece. Specifically, by 370 B.C., at the most important healing sanctuary in the wider area, the Sanctuary of Asclepius at Epidaurus , there were at least 11 permanent stone ramps that provided access to mobility-impaired visitors to nine different structures; evidence that people with disabilities were acknowledged and cared for, at least partly, in ancient Greece. In fact,

3850-690: The groups targeted by the Nazi regime in Germany, resulting in approximately 250,000 disabled people being killed during the Holocaust . At the end of the Second World War , with the example of Nazi eugenics , eugenics faded from public discourse , and increasingly disability cohered into a set of attributes to which medicine could attend – whether through augmentation, rehabilitation, or treatment. In both contemporary and modern history, disability

3927-474: The individual. A disability may be readily visible, or invisible in nature. The United Nations Convention on the Rights of Persons with Disabilities defines disability as including: long-term physical, mental, intellectual or sensory impairments which in interaction with various barriers may hinder [a person's] full and effective participation in society on an equal basis with others. Disabilities have been perceived differently throughout history, through

4004-404: The individuals represent to majior factors influencing building evacuations. With increasing complexity and decreasing motion ability, the strategy changes from "fast egress", through "slow egress" and "move to safe place inside building" (such as a staircase), to "stay in place and wait for help". The third strategy is the notion of using a designated "safe haven" on the floor. This is a section of

4081-508: The law—though there are still political issues that enable or advance the oppression of disabled people. Although disability activism serves to dismantle ableist systems, social norms relating to the perception of disabilities are often reinforced by tropes used by the media. Since negative perceptions of disability are pervasive in modern society, disabled people have turned to self-advocacy in an attempt to push back against their marginalization. The recognition of disability as an identity that

4158-408: The medical approach to disability. Due to this work, physical barriers to access were identified. These conditions functionally disabled them, and what is now known as the social model of disability emerged. Coined by Mike Oliver in 1983, this phrase distinguishes between the medical model of disability – under which an impairment needs to be fixed – and the social model of disability – under which

4235-562: The medical model, medical care is viewed as the main issue, and at the political level, the principal response is that of modifying or reforming healthcare policy. The medical model focuses on finding causes and cures for disabilities. There are many causes of disability that often affect basic activities of daily living , such as eating, dressing, transferring, and maintaining personal hygiene ; or advanced activities of daily living such as shopping, food preparation, driving, or working. However, causes of disability are usually determined by

4312-431: The most resistant to evacuating. Since Hurricane Katrina, there has been an increase in evacuation planning. Current best practices include the need to use multi-modal transportation networks. Hurricane Gustav used military airlift resources to facilitate evacuating people out of the affected area. More complex evacuation planning is now being considered, such as using elementary schools as rally points for evacuation. In

4389-434: The names and contact of their next-of-kin, writing their Social Security Numbers on their limbs and torso to enable identification of remains, and refusing to provide government services in the affected area, including emergency services. In preparation for emergency evacuation situations, experts often advise having an individual emergency evacuation kit prepared and on hand prior to the emergency. An emergency evacuation kit

4466-556: The natural order, especially during and in the fallout of the Black Death , which wrought impairments throughout the general population. In the early modern period there was a shift to seeking biological causes for physical and mental differences, as well as heightened interest in demarcating categories: for example, Ambroise Pare, in the sixteenth century, wrote of "monsters", "prodigies", and "the maimed". The European Enlightenment 's emphases on knowledge derived from reason and on

4543-457: The need for a new model that will overcome the "medical vs. social" dichotomy. The limitations of this model mean that often the vital services and information persons with disabilities face are simply not available, often due to limited economic returns in supporting them. Some say medical humanities is a fruitful field where the gap between the medical and the social model of disability might be bridged. The social construction of disability

4620-493: The nineteenth century, such deviations were viewed as dangerous to the health of entire populations. With disability viewed as part of a person's biological make-up and thus their genetic inheritance, scientists turned their attention to notions of weeding such as "deviations" out of the gene pool. Various metrics for assessing a person's genetic fitness were determined and were then used to deport , sterilize, or institutionalize those deemed unfit. People with disabilities were one of

4697-503: The non- ambulatory people. Regulations such as building codes can be used to minimize the negative consequences of the threat triggering the evacuation and optimize the need to self-evacuate without causing alarm. Proper planning, that covers designated actions to ensure safety of the users in emergencies, will implement an all-hazards approach so that plans can be reused for multiple hazards that could exist. Therefore, key elements for emergency planning and preparedness are early warnings for

4774-506: The people inside the building by emergency helpers but also voice assistance, facilities to leave the building safe and fast, such as exit routes and good evacuation practices. The evacuation managing team must know what to do in emergency situations and which actions to take. The sequence of an evacuation can be divided into the following phases: The time for the first four phases is usually called pre-movement time . The particular phases are different for different objects, e.g., for ships

4851-578: The purposes of the Americans with Disabilities Act of 1990 , the US Equal Employment Opportunity Commission regulations provide a list of conditions that should easily be concluded to be disabilities: amputation , attention deficit hyperactivity disorder (ADHD), autism , bipolar disorder , blindness , cancer , cerebral palsy , deafness , diabetes , epilepsy , HIV/AIDS , intellectual disability , major depressive disorder , mobility impairments requiring

4928-593: The safest and most efficient evacuation time of all expected residents of a structure, city, or region. A benchmark "evacuation time" for different hazards and conditions is established. These benchmarks can be established through using best practices, regulations, or using simulations , such as modeling the flow of people in a building, to determine the benchmark. Proper planning will use multiple exits, contra-flow lanes , and special technologies to ensure full, fast and complete evacuation. Consideration for personal situations which may affect an individual's ability to evacuate

5005-655: The same way one refers to 'Muslims,' 'African-Americans,' 'Lesbian/Gay/Bisexual/Transgender/Queer,' 'Chinese,' 'gifted,' 'athletic,' or 'Jewish.' Similarly, Deaf communities in the US reject people-first language in favor of identity-first language. In 2021, the US Association on Higher Education and Disability (AHEAD) announced their decision to use identity-first language in their materials, explaining: "Identity-first language challenges negative connotations by claiming disability directly. Identity-first language references

5082-486: The skeletons was a male about 15 years old who had spina bifida . The condition meant that the boy, probably paralyzed below the waist, was taken care of in a hunter-gatherer community. Disability was not viewed as a means of divine punishment and therefore disabled individuals were neither exterminated nor discriminated against for their impairments. Many were instead employed in different levels of Mesopotamian society including working in religious temples as servants of

5159-461: The society that limits a person needs to be fixed. Like many social categories, the concept of "disability" is under heavy discussion amongst academia, the medical and legal worlds, and the disability community. The academic discipline focused on theorizing disability is disability studies , which has been expanding since the late twentieth century. The field investigates the past, present, and future constructions of disability, along with advancing

5236-427: The strategy of individuals in evacuating buildings, the variable human reactions is a complex factor to take into account during an evacuation. This is a critical factor for escaping fast out of the building or to a "safe haven". During an emergency evacuation, people do not immediately react after hearing the alarm signal. This is because an evacuation drill is more common. Therefore, they will start evacuating when there

USS  Cape Cod was the first ship to enter Subic Bay and provided fresh water, manufactured coffins and volcanic ash shovels to assist SRF Subic Bay and the base with recovery and rescue operations. Emergency evacuation Examples range from the small-scale evacuation of

5390-416: The value of natural science to human progress helped spawn the birth of institutions and associated knowledge systems that observed and categorized human beings; among these, the ones significant to the development of today's concepts of disability were asylums , clinics , and prisons . Contemporary concepts of disability are rooted in eighteenth- and nineteenth-century developments. Foremost among these

5467-511: The variety that exists in how our bodies and brains work with a myriad of conditions that exist, and the role of inaccessible or oppressive systems, structures, or environments in making someone disabled." Invisible disabilities, also known as Hidden Disabilities or Non-visible Disabilities (NVD), are disabilities that are not immediately apparent, or seeable. They are often chronic illnesses and conditions that significantly impair normal activities of daily living. Invisible disabilities can hinder

5544-439: The viewpoint that disability is a complex social identity from which we can all gain insight. As disabilities scholar Claire Mullaney puts it, "At its broadest, disability studies encourages scholars to value disability as a form of cultural difference". Scholars of the field focus on a range of disability-related topics, such as ethics, policy and legislation, history, art of the disability community, and more. Notable scholars from

5621-528: The way bodies were viewed as people were increasingly valued for their ability to produce like machines. Capitalism and the industrial revolution effectively solidified this class of "disabled" people who could not conform to the standard worker 's body or level of work power. As a result, disabled people came to be regarded as a problem, to be solved or erased. In the early 1970s, the disability rights movement became established, when disability activists began to challenge how society treated disabled people and

5698-570: Was designed in New Zealand specifically for persons with disabilities. The World Wide Web consortium recognized a need for International Standards for Web Accessibility for persons with disabilities and created the Web Accessibility Initiative (WAI). As at Dec 2012 the standard is WCAG 2.0 (WCAG = Web Content Accessibility Guidelines). The social model of disability sees "disability" as a socially created problem and

5775-476: Was often viewed as a by-product of incest between first-degree relatives or second-degree relatives . Disability scholars have also pointed to the Industrial Revolution , along with the economic shift from feudalism to capitalism , as prominent historical moments in the understanding of disability. Although there was a certain amount of religious superstition surrounding disability during

These worked in tandem with scientific discourses that sought to classify and categorize and, in so doing, became methods of normalization . The concept of the "norm" developed in this time period, and is signaled in the work of the Belgian statistician , sociologist , mathematician , and astronomer Adolphe Quetelet , who wrote in

The eruption produced high-speed pyroclastic flows, giant lahars , and a cloud of volcanic ash hundreds of miles across. Twenty million tons of sulfur dioxide and roughly 11 cubic kilometers (2.6 cu mi) of tephra are estimated to have been ejected in total, which corresponds to
