Bicameralism (Psychology)
Bicameralism[Note 1] (the condition of being divided into "two-chambers") is a controversial hypothesis in psychology and neuroscience which argues that the human mind once operated in a state in which cognitive functions were divided between one part of the brain which appears to be "speaking", and a second part which listens and obeys—a bicameral mind, and that the evolutionary breakdown of this division gave rise to consciousness in humans. The term was coined by Julian Jaynes, who presented the idea in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wherein he made the case that a bicameral mentality was the normal and ubiquitous state of the human mind as recently as 3,000 years ago, near the end of the Mediterranean bronze age.

Penn State Child Sex Abuse Scandal
The Penn State child sex abuse scandal concerned allegations and subsequent convictions of child sexual abuse committed by Jerry Sandusky, an assistant coach for the Penn State Nittany Lions football team, over a period of at least fifteen years. The scandal began to emerge publicly in March 2011 and broke in early November 2011 when Sandusky was indicted on 52 counts of child molestation, stemming from incidents that occurred between 1994 and 2009. Sandusky was ultimately convicted on 45 counts of child sexual abuse on June 22, 2012, and was sentenced to a minimum of 30 years and a maximum of 60 years in prison. Additionally, three Penn State officials – school president Graham Spanier, vice president Gary Schultz and athletic director Tim Curley – were charged with perjury, obstruction of justice, failure to report suspected child abuse, and related charges. The Penn State Board of Trustees commissioned an independent investigation by former FBI Director Louis Freeh, whose report stated that Penn State's longtime head football coach Joe Paterno, along with Spanier, Curley and Schultz, had known about allegations of child abuse by Sandusky as early as 1998, had shown "total and consistent disregard...for the safety and welfare of Sandusky's child victims", and "empowered" Sandusky to continue his acts of abuse by failing to disclose them.:14 Shortly after the scandal broke, Spanier resigned. The Board of Trustees terminated the contracts of Paterno and Curley. As a result of the scandal, the National Collegiate Athletic Association (NCAA) imposed sanctions on the Penn State football program: a $60 million fine, a four-year postseason ban, scholarship reductions, and a vacation of all victories from 1998 to 2011. These sanctions were considered to be among the most severe ever imposed on an NCAA member school. NCAA President Mark Emmert stated that the sanctions were levied "not to be just punitive, but to make sure the university establishes an athletic culture and daily mindset in which football will never again be placed ahead of educating, nurturing and protecting young people." The Big Ten Conference subsequently imposed an additional $13 million fine. The Paterno family retained former Attorney General Richard Thornburgh to conduct a review of the Freeh report, which concluded that the report constituted a "rush to injustice" that could not be relied upon and that Freeh's evidence fell "far short" of showing that Joe Paterno attempted to conceal the scandal, but rather that "the contrary is true". In January 2013, state senator Jake Corman and state treasurer Rob McCord sued the NCAA, seeking to overturn the Penn State sanctions on the basis that Freeh had been actively collaborating with the organization and that due process had not been followed. In November 2014, Corman released emails showing "regular and substantive" contact between Freeh's investigators and the NCAA, suggesting that Freeh's conclusions were orchestrated. As part of a settlement, the NCAA restored the 111 wins to Paterno's record on January 16, 2015. On March 25, 2017, Curley, Schultz, and Spanier pleaded or were found guilty of misdemeanor charges of child endangerment. All conspiracy charges against Curley and Schultz were dropped, and Spanier was acquitted of conspiracy, the charges central to Louis Freeh's allegation of a cover-up. In June 2017, all three were sentenced to jail terms, fines, and probation for the misdemeanors. Spanier was sentenced to four to twelve months in jail, a $7,500 fine, and two years of probation. Spanier's misdemeanor conviction was subsequently overturned on appeal.

First Bulgarian Empire
The First Bulgarian Empire (Old Bulgarian: ц︢рьство бл︢гарское, ts'rstvo bl'garskoe) was a medieval Bulgarian state that existed in Southeastern Europe between the 7th and 11th centuries AD. It was founded in 681 when Bulgar tribes led by Asparuh moved to the northeastern Balkans. There they secured Byzantine recognition of their right to settle south of the Danube by defeating – possibly with the help of local South Slavic tribes – the Byzantine army led by Constantine IV. At the height of its power, Bulgaria spread from the Danube Bend to the Black Sea and from the Dnieper River to the Adriatic Sea. As the state solidified its position in the Balkans, it entered into a centuries-long interaction, sometimes friendly and sometimes hostile, with the Byzantine Empire. Bulgaria emerged as Byzantium's chief antagonist to its north, resulting in several wars. The two powers also enjoyed periods of peace and alliance, most notably during the Second Arab siege of Constantinople, where the Bulgarian army broke the siege and destroyed the Arab army, thus preventing an Arab invasion of Southeastern Europe. Byzantium had a strong cultural influence on Bulgaria, which also led to the eventual adoption of Christianity in 864. After the disintegration of the Avar Khaganate, the country expanded its territory northwest to the Pannonian Plain. Later the Bulgarians confronted the advance of the Pechenegs and Cumans, and achieved a decisive victory over the Magyars, forcing them to establish themselves permanently in Pannonia. During the late 9th and early 10th centuries, Simeon I achieved a string of victories over the Byzantines. Thereafter, he was recognized with the title of Emperor, and proceeded to expand the state to its greatest extent. After the annihilation of the Byzantine army in the battle of Anchialus in 917, the Bulgarians laid siege to Constantinople in 923 and 924. The Byzantines, however, eventually recovered, and in 1014, under Basil II, inflicted a crushing defeat on the Bulgarians at the Battle of Kleidion. By 1018, the last Bulgarian strongholds had surrendered to the Byzantine Empire, and the First Bulgarian Empire had ceased to exist. It was succeeded by the Second Bulgarian Empire in 1185. After the adoption of Christianity, Bulgaria became the cultural center of Slavic Europe. Its leading cultural position was further consolidated with the invention of the Glagolitic and Early Cyrillic alphabets shortly after in the capital Preslav, and literature produced in Old Bulgarian soon began spreading north. Old Bulgarian became the lingua franca of much of Eastern Europe and it came to be known as Old Church Slavonic. In 927, the fully independent Bulgarian Patriarchate was officially recognized. The ruling Bulgars and other non-Slavic tribes in the empire gradually mixed and adopted the prevailing Slavic language, thus gradually forming the Bulgarian nation from the 7th century to the 9th century. Since the late 9th century, the names Bulgarians and Bulgarian gained prevalence and became permanent designations for the local population, both in literature and in common parlance. The development of Old Church Slavonic literacy had the effect of preventing the assimilation of the South Slavs into neighbouring cultures, while stimulating the formation of a distinct Bulgarian identity.

Anthropomorphism on Dog Emotions and Behavior
Anthropomorphism is defined as the tendency to attribute human forms, behaviors, and emotions to non-human animals or objects. Anthropomorphism is particularly relevant for companion animals. Some anthropomorphic practices can be beneficial to them, whilst others can be very detrimental. Some anthropomorphic behaviors compromise the welfare and physiology of animals by interfering with thermoregulation, while others can produce dehydration due to the loss of body water, a condition that brings undesirable consequences such as high compensatory blood pressure and heat shock, even death, depending on the intensity and frequency of an animal’s exposure to these stressors.

Synthesis and Properties of Pyrazoles
Pyrazole derivatives are a special class of N-heterocyclic compounds (NHCps) bearing a heteroaromatic five-membered ring with two adjacent nitrogen atoms in the annular structure, one pyrrole-type (proton donor) and one pyridine-type (proton acceptor). Pyrazoles can act as weak bases or acids, with possible strength highly dependent on the nature of their substituent groups. The other three positions in the ring permit structural variants starting from the appropriate precursors or using post-functionalization reactions once the pyrazole ring is formed; these variations give the pyrazoles diverse and valuable synthetical, biological, and photophysical properties; indeed, more complex structures with various relevant examples can be formed from them.

United Express Flight 3411 Incident
Template:Infobox Aircraft occurrence The United Express Flight 3411 incident occurred at Chicago O'Hare International Airport, United States on April 9, 2017, when Dr. David Dao Duy Anh, a Vietnamese-American passenger, was injured while being forcibly removed from a fully boarded, sold-out flight to Louisville International Airport. Dao, a pulmonologist and folk musician, refused to surrender his seat when requested because he needed to see patients the following day. Chicago Department of Aviation Security officers were called to remove him from the plane; in the process, they struck Dao's face against an armrest, then pulled him, apparently unconscious, by his arms along the aircraft aisle past rows of onlooking passengers. Prior to the confrontation, United agents offered travel vouchers to passengers to vacate their seats to make room for four deadheading Republic Airways employees, but none of the passengers accepted. United then selected four passengers for involuntary removal from the flight, one of whom was Dao, and the three other passengers agreed to leave. Flight 3411 was operated by Republic Airways on behalf of United Express, a United Airlines regional branch. Video of the incident recorded by passengers went viral on social media, resulting in anger over the force that was used. Politicians expressed concern and called for an official investigation. Then-U.S. President Donald Trump criticized United Airlines, calling its treatment of Dao "horrible." The next morning, then-CEO of United, Oscar Munoz, issued a statement that appeared to justify the removal of Dao, referring to "re-accommodating the customers." Munoz also sent an email to United staff commending the crew's actions for following established procedures and referring to Dao as "disruptive" and "belligerent," though this characterization contradicted passengers' accounts of the incident. Passenger Jason Powell asserted that Dao was not belligerent, saying instead, "He was very polite, matter-of-fact." Cell phone video by passenger Joya Cummings also contradicted Munoz's description of Dao as belligerent. Munoz and United were sharply criticized for their initial statements, and United suffered a drop in its stock price. Two days after the incident, Munoz issued an additional statement, apologizing and promising that such an incident would never again occur on a United aircraft. He said, "No one should ever be mistreated this way." In an ABC television interview, Munoz was asked, "Do you think [Dao] was at fault in any way?" Munoz responded, "No. He can't be. He was a paying passenger sitting on our seat in our aircraft." Munoz's previously planned promotion to become United's chairman was delayed until May 2020 as a result of the incident. Dao reached an "amicable" settlement with United on April 27, 2017, though its terms were not publicly announced.

Records Continuum Model
The Records Continuum Model (RCM) was created in the 1990s by Monash University academic Frank Upward with input from colleagues Sue McKemmish and Livia Iacovino as a response to evolving discussions about the challenges of managing digital records and archives in the discipline of Archival Science. The RCM was first published in Upward’s 1996 paper "Structuring the Records Continuum – Part One: Postcustodial principles and properties". Upward describes the RCM within the broad context of a continuum where activities and interactions transform documents into records, evidence and memory that are used for multiple purposes over time. Upward places the RCM within a post-custodial, postmodern and structuration conceptual framework. Australian academics and practitioners continue to explore, develop and extend the RCM and records continuum theory, along with international collaborators, via the Records Continuum Research Group (RCRG) at Monash University.

Context-Dependent Memory
In psychology, context-dependent memory is the improved recall of specific episodes or information when the context present at encoding and retrieval are the same. In a simpler manner, "when events are represented in memory, contextual information is stored along with memory targets; the context can therefore cue memories containing that contextual information". One particularly common example of context-dependence at work occurs when an individual has lost an item (e.g. lost car keys) in an unknown location. Typically, people try to systematically "retrace their steps" to determine all of the possible places where the item might be located. Based on the role that context plays in determining recall, it is not at all surprising that individuals often quite easily discover the lost item upon returning to the correct context. This concept is heavily related to the encoding specificity principle. This example best describes the concept of context-dependent forgetting. However, the research literature on context-dependent memory describes a number of different types of contextual information that may affect recall such as environmental context-dependent memory, state-dependent learning, cognitive context-dependent memory and mood-congruent memory. Research has also shown that context-dependence may play an important role in numerous situations, such as memory for studied material, or events that have occurred following the consumption of alcohol or other drugs.
