Question: David upheld his support for his niece, the former Empress-consort, who had how many children?
Context: The Children's Crusade was a march by hundreds of school students in Birmingham, Alabama, May 2–5, 1963, during the Civil Rights Movement's Birmingham campaign.  Initiated and organized by Rev. James Bevel, the purpose of the march was to walk downtown to talk to the mayor about segregation in their city.  Many children left their schools and were arrested, set free, and then arrested again the next day.  The marches were stopped by the head of police, Bull Connor, who brought fire hoses to ward off the children, and set police dogs after the children.  This event compelled President John F. Kennedy to publicly support federal civil rights legislation, and eventually led to the passage of the Civil Rights Act of 1964. Pain management in children is the assessment and treatment of pain in infants and children.  Pain has many definitions.  It is described as a sensation of anxiety, discomfort and distress.  Physiologically, pain can be described in terms of nerve stimulation and conduction of nerve impulses to the brain.  Such stimulation can be mild, localized, chronic, acute or agonizing.  Even in children, pain is tied to emotional and psychological components.  The consequences of untreated pain can increase the incidence of further complications and even death.  Children can have significant pain related to Epidermolysis Bullosa, Osteogenesis Imperfecta, cancer, metabolic/neurologic diseases, palliative care, and sickle cell disease.  One clinician has described the use of evidence-based approaches to managing pain in children: "Pain management practices should be based on scientific facts or agreed best practices, not on personal beliefs or opinion.  The burden of proof lies with the healthcare professional, NOT the patient."  The pain of many children is undertreated. The history of Sherman is linked with Valentine Walter family's history.  Valentine and his wife came from Eureka and had homesteaded in Sherman Creek by 1876.  The couple had twelve children.  Because he had so many children, Walter had the permission to open and to create his own school district on May 9, 1886.  Sherma was a stagecoach stop.  The Walthers provided food and lodging.  Walther had the finest grove in Nevada at that time.  In this orchard he raised cherries, plums, apricots, apples (250 apple trees).  Unhappily, Mrs Walther died in June 1895 and Valentine was left alone to raise 11 children (one child had died at two months of age).  In 1902, he and a friend began to build a huge nine-room log home which took 2 years to finish.  In 1922, Walther sold his ranch and retired to Elko, where he died in 1933.  Nowadays, Sherman is a private property behind a gate and should not be entered without permission, but many of the buildings of early times remain, such as a blacksmith shop and the school. Hagwon (] ) is the Korean-language word for a for-profit private institute, academy or cram school prevalent in South Korea.  Although most widely known for their role as "cram schools", where children can study to improve scores, hagwon actually perform several educational functions: they provide supplementary education that many children need just to keep up with the regular school curriculum, remedial education for the children who fall behind in their work, training in areas not covered in schools, and preparation for students striving to improve test scores and preparing for the high school and university entrance examinations (the university entrance exam is also called suneung (수능)).  Many other children, particularly younger children, attend nonacademic hagwon for piano lessons, art instruction, swimming, and taekwondo (태권도).  Most young children attend a hagwon.  Hagwon also play a social role, and many children, especially the younger ones, say they like going to hagwon because they are able to make new friends; many children ask to be sent because their friends attend.  There are many hagwon for adults too, such as flower arrangement and driving-license hagwon.  The term is also sometimes used to describe similar institutions operated by Korean Americans in the United States. Stranger danger is the idea or warning that all strangers can potentially be dangerous to children and adults.  It is an example of a moral panic that people experience regarding anyone that they are unfamiliar with in society.  The phrase "stranger danger" is intended to sum up the danger associated with adults whom adults or children do not know.  The phrase has found widespread usage and many children will hear it during their childhood lives.  Many books, films and public service announcements have been devoted to helping children remember this advice.  The concept has been criticized for ignoring that most child abductions and harm result not from strangers, but rather from someone the child knows. The relationship between the Kingdom of England and King David I, who was King of Scotland between 1124 and 1153, was partly shaped by David's relationship with the particular King of England, and partly by David's own ambition.  David had a good relationship with and was an ally of Henry I of England, the King who was largely responsible for David's early career.  After Henry's death, David upheld his support for his niece, the former Empress-consort, Matilda, and expanded his power in northern England in the process, despite his defeat at the Battle of the Standard in 1138. No Jumping on the Bed!  is a children's book written and illustrated by Tedd Arnold.  Published in 1987, it marked the first of the many children's books that Arnold was to both write and illustrate.  "No Jumping on the Bed!"  won the 1988 International Reading Association/Children's Book Council Children's Choice Award, the Georgia Children's Picture Storybook Award in 1990, and the Volunteer State Book Award in 1992.  The book is aimed at 4-7 year olds and written in humorous rhyming prose, similar in style to that of Dr. Seuss whom Arnold acknowledges as a major influence on his work.  It tells the story of Walter, a little boy whose father has told not to jump up and down on his bed.  Walter dreams that he has ignored his father's warning with disastrous results.  He and his bed fall through all seven floors of his apartment building, taking with them all the neighbors in the floors below. Chest pain in children is the pain felt in the chest by infants, children and adolescents.  In most cases the pain is not associated with the heart.  It is primarily identified by the observance or report of pain by the infant, child or adolescent by reports of distress by parents or caregivers.  Chest pain is not uncommon in children.  Many children are seen in ambulatory clinics, emergency departments and hospitals and cardiology clinics.  Most often there is a benign cause for the pain for most children.  Some have conditions that are serious and possibly life-threatening.  Chest pain in pediatric patients requires careful physical examination and a detailed history that would indicate the possibility of a serious cause.  Studies of pediatric chest pain are sparse.  It has been difficult to create evidence-based guidelines for evaluation. Camp Lanowa, and its sister Camps of Kiwago and Wakonda, are non-profit camps run by Homes for the Homeless, a non-profit operator of homeless shelters in New York City.  Homelessness is a worrying and relatively large problem in New York City, with approximately 100,000 experiencing homelessness each year.  Such an environment can frequently lead to a difficult upbringing for children unfortunate enough to find themselves in this position.  The result is that many children grow up unable to experience the sort of childhood so often taken for granted; material goods are often unattainable; on occasion families cannot afford to adequately clothe or even feed their children and additionally, such children miss out on experiences often regarded as a rite of passage, instead condemned to a childhood of tough city living.  Against this background, Camp Lanowa and its sister camps attempt to offer such opportunities to these children and provide an escape from the tough inner city life. Empress Matilda (c. 7 February 110210 September 1167), also known as the Empress Maude, was the claimant to the English throne during the civil war known as the Anarchy.  The daughter of King Henry I of England, she moved to Germany as a child when she married the future Holy Roman Emperor Henry V.  She travelled with her husband into Italy in 1116, was controversially crowned in St. Peter's Basilica, and acted as the imperial regent in Italy.  Matilda and Henry had no children, and when Henry died in 1125, the crown was claimed by Lothair II, one of his political enemies.
