Developmental Disorder
Developmental disorders comprise a group of psychiatric conditions originating in childhood that involve serious impairment in different areas. There are several ways of using this term. The most narrow concept is used in the category "Specific Disorders of Psychological Development" in the ICD-10. These disorders comprise developmental language disorder, learning disorders, motor disorders, and autism spectrum disorders. In broader definitions ADHD is included, and the term used is neurodevelopmental disorders. Yet others include antisocial behavior and schizophrenia that begins in childhood and continues through life. However, these two latter conditions are not as stable as the other developmental disorders, and there is not the same evidence of a shared genetic liability. Developmental disorders are present from early life. Most improve as the child grows older, but some entail impairments that continue throughout life.

Negawatt Power
Negawatt power is a theoretical unit of power representing an amount of electrical power (measured in watts) saved. The energy saved is a direct result of energy conservation or increased energy efficiency. The term was coined by the chief scientist of the Rocky Mountain Institute and environmentalist Amory Lovins in 1985, within the article, "Saving Gigabucks with Negawatts," where he argued that utility customers don’t want kilowatt-hours of electricity; they want energy services such as hot showers, cold beer, lit rooms, and spinning shafts, which can come more cheaply if electricity is used more efficiently. Lovins felt an international behavioral change was necessary in order to decrease countries' dependence on excessive amounts of energy. The concept of a negawatt could influence a behavioral change in consumers by encouraging them to think about the energy that they spend. A negawatt market can be thought of as a secondary market, in which electricity is allocated from one consumer to another consumer within the energy market. In this market, negawatts could be treated as a commodity. Commodities have the ability to be traded across time and space, which would allow negawatts to be incorporated in the international trading system. Roughly 10% of all U.S. electrical generating capacity is in place to meet the last 1% of demand and there is where the immediate efficiency opportunity exists. On March 15, 2011, the Federal Energy Regulatory Commission (FERC), the agency that regulates the U.S. electrical grid, approved a rule establishing the approach to compensation for demand response resources intended to benefit customers and help improve the operation and competitiveness of organized wholesale energy markets. This means that negawatts produced by reducing electrical use can demand the same market prices as real megawatts of generated electricity. The incentives for a negawatt market include receiving money, reduction of national energy dependency, and the local electricity deregulation within certain nations or states. As for the cost incentive, those who produce negawatts or simply conserve energy can earn money by selling the saved energy. The negawatt market could help nations or states obtain a deregulated electricity system by creating another market to purchase electricity from. The negawatt market also has two main drawbacks. Currently, there is no way to precisely measure the amount of energy saved in negawatts, and electricity providers may not want customers to use less energy due to the loss of profit.

Collections Management (Museum)
Collections management involves the development, storage, and preservation of collections and cultural heritage. The primary goal of collections management is to meet the needs of the individual collector or collecting institution's mission statement, while also ensuring the long-term safety and sustainability of the cultural objects within the collector's care. Collections management, which consists primarily of the administrative responsibilities associated with collection development, is closely related to collections care, which is the physical preservation of cultural heritage. The professions most influenced by collections management include collection managers, registrars, and archivists.

Whataboutism
Whataboutism, also known as whataboutery, is a variant of the tu quoque logical fallacy that attempts to discredit an opponent's position by charging them with hypocrisy without directly refuting or disproving their argument. According to Russian writer, chess grandmaster and political activist Garry Kasparov, "whataboutism" is a word that was coined to describe the frequent use of a rhetorical diversion by Soviet apologists and dictators, who would counter charges of their oppression, "massacres, gulags, and forced deportations" by invoking American slavery, racism, lynchings, etc. Whataboutism has been used by other politicians and countries as well. Whataboutism is particularly associated with Soviet and Russian propaganda. When criticisms were leveled at the Soviet Union during the Cold War, the Soviet response would often use "and what about you?" style by instancing of an event or situation in the Western world. The idea can be found in Russian language: while it utilizes phrase "Sam takoi" for direct tu quoque-like "you too"; it also has "Sam ne lutche" ("not better") phrase.

Abusive Head Trauma
Abusive head trauma (AHT), commonly known as shaken baby syndrome (SBS), is an injury to a child's head caused by someone else. Symptoms may range from subtle to obvious. Symptoms may include vomiting or a baby that will not settle. Often there are no visible signs of trauma. Complications include seizures, visual impairment, cerebral palsy, and cognitive impairment. The cause may be blunt trauma or vigorous shaking. Often this occurs as a result of a caregiver becoming frustrated due to the child crying. Diagnosis can be difficult as symptoms may be nonspecific. A CT scan of the head is typically recommended if a concern is present. While retinal bleeding is common, it can also occur in other conditions. Abusive head trauma is a type of child abuse. Educating new parents appears to be beneficial in decreasing rates of the condition. Treatment occasionally requires surgery, such as to place a cerebral shunt. AHT is estimated to occur in 3 to 4 per 10,000 babies a year. It occurs most frequently in those less than five years of age. The risk of death is about 25%. The diagnosis may also carry legal consequences for the parents.

List of Submarines of Submarine Force Command
The Argentine Submarine Force (Spanish: Comando de la Fuerza de Submarinos, COFS) is the submarine service branch of the Argentine Navy. Argentine submarines have traditionally been named after the provinces of the Republic whose name begins with the letter 'S'; they are home based at Mar del Plata naval base. COFS members have the same rank insignia and titles as the rest of the Navy. As of 2010, the elite group Agrupación de Buzos Tácticos is under the direct command of the submarine force. After the disappearance of ARA San Juan in November 2017, one TR-1700 (ARA Santa Cruz (S-41)) and one Type 209 (ARA Salta (S-31)) submarines are in service. Two small surface vessels, ARA Punta Mogotes (P-65) and ARA Luisito (Q-51), are also part of the COFS and used in the training role. Like the rest of the Argentine armed services, the submarine force has been struggling to maintain its readiness due to budget constraints affecting equipment maintenance and personnel training. In 2012, the three boats then in service had maintenance difficulties and between them spent just 19 hours submerged.

Forensic Dentistry
Forensic dentistry or forensic odontology involves handling, examination and evaluation of dental evidence in criminal justice cases. Forensic dentists are involved in assisting investigative agencies to identify recovered human remains in addition to the identification of whole or fragmented bodies. Forensic dentists have also been known to use their investigative techniques to identify burn victims by using the victims previous dental records. Forensic dentists may also be asked to assist in determining age, race, occupation, previous dental history and socioeconomic status of unidentified human beings. The evidence that may be derived from teeth is the age (in children) and identification of the person to whom the teeth belong. This is done using dental records including radiographs, ante-mortem (prior to death) and post-mortem (after death) photographs and DNA. Another type of evidence is that of bite marks, left on either the victim (by the attacker), the perpetrator (from the victim of an attack), or on an object found at the crime scene. Bite mark analysis has been condemned by several scientific bodies, such as the National Academy of Sciences (NAS), the President's Council of Advisors on Science and Technology (PCAST), and the Texas Forensic Science Commission. No scientific studies or evidence substantiate that bite marks can demonstrate sufficient detail for positive identification. There are numerous instances where experts diverge widely in their evaluations of the same bite mark evidence.

Five Precepts
The five precepts (Pali: pañcasīla; Sanskrit: pañcaśīla) or five rules of training (Pali: pañcasikkhapada; Sanskrit: pañcaśikṣapada) is the most important system of morality for Buddhist lay people. They constitute the basic code of ethics undertaken by lay followers of Buddhism. The precepts are commitments to abstain from killing living beings, stealing, sexual misconduct, lying and intoxication. Within the Buddhist doctrine, they are meant to develop mind and character to make progress on the path to enlightenment. They are sometimes referred to as the śrāvakayāna precepts in the Mahāyāna tradition, contrasting them with the bodhisattva precepts. The five precepts form the basis of several parts of Buddhist doctrine, both lay and monastic. With regard to their fundamental role in Buddhist ethics, they have been compared with the ten commandments in Christianity or the ethical codes of Confucianism. The precepts have been connected with utilitarianist, deontological and virtue approaches to ethics. They have been compared with human rights because of their universal nature, and some scholars argue they can complement the concept of human rights. The five precepts were common to the religious milieu of 6th-century BCE India, but the Buddha's focus on awareness through the fifth precept was unique. As shown in Early Buddhist Texts, the precepts grew to be more important, and finally became a condition for membership of the Buddhist religion. When Buddhism spread to different places and people, the role of the precepts began to vary. In countries where Buddhism had to compete with other religions, such as China, the ritual of undertaking the five precepts developed into an initiation ceremony to become a Buddhist lay person. On the other hand, in countries with little competition from other religions, such as Thailand, the ceremony has had little relation to the rite of becoming Buddhist, as many people are presumed Buddhist from birth. Undertaking and upholding the five precepts is based on the principle of non-harming (Pāli and Sanskrit: ahiṃsa). The Pali Canon recommends one to compare oneself with others, and on the basis of that, not to hurt others. Compassion and a belief in karmic retribution form the foundation of the precepts. Undertaking the five precepts is part of regular lay devotional practice, both at home and at the local temple. However, the extent to which people keep them differs per region and time. People keep them with an intention to develop themselves, but also out of fear of a bad rebirth. The first precept consists of a prohibition of killing, both humans and all animals. Scholars have interpreted Buddhist texts about the precepts as an opposition to and prohibition of capital punishment, suicide, abortion and euthanasia. In practice, however, many Buddhist countries still use the death penalty. With regard to abortion, Buddhist countries take the middle ground, by condemning though not prohibiting it. The Buddhist attitude to violence is generally interpreted as opposing all warfare, but some scholars have raised exceptions. The second precept prohibits theft. The third precept refers to adultery in all its forms, and has been defined by modern teachers with terms such as sexual responsibility and long-term commitment. The fourth precept involves falsehood spoken or committed to by action, as well as malicious speech, harsh speech and gossip. The fifth precept prohibits intoxication through alcohol, drugs or other means. Early Buddhist Texts nearly always condemn alcohol, and so do Chinese Buddhist post-canonical texts. Buddhist attitudes toward smoking differ per time and region, but are generally permissive. In modern times, traditional Buddhist countries have seen revival movements to promote the five precepts. As for the West, the precepts play a major role in Buddhist organizations. They have also been integrated in mindfulness training programs, though many mindfulness specialists do not support this because of the precepts' religious import. Lastly, many conflict prevention programs make use of the precepts.
