Reactance (Psychology)
Reactance is an unpleasant motivational arousal (reaction) to offers, persons, rules, or regulations that threaten or eliminate specific behavioral freedoms. Reactance occurs when a person feels that someone or something is taking away their choices or limiting the range of alternatives. Reactance can occur when someone is heavily pressured to accept a certain view or attitude. Reactance can cause the person to adopt or strengthen a view or attitude that is contrary to what was intended, and also increases resistance to persuasion. People using reverse psychology are playing on reactance, attempting to influence someone to choose the opposite of what they request. Some individuals are naturally high in reactance, a personality characteristic called trait reactance.

Quadjet
A quadjet or four-engine jet is a jet aircraft powered by four engines. The presence of four engines offers increased power output and redundancy, allowing quadjets to be used as civilian airliners, freighters and military aircraft. Many of the first purpose-built jetliners were quadjets, among which stands the De Havilland Comet, the world's first commercial jetliner. In the past two decades, the use of quadjet airliners has gradually begun to decline due to a variety of factors, including the approval of twinjets to fly further from diversion airports and an increased emphasis on fuel efficiency.

BBM
BBM, also known by its full name BlackBerry Messenger, was a proprietary mobile instant messenger and videotelephony application included on BlackBerry devices that allows messaging and voice calls between BlackBerry OS, BlackBerry 10, iOS, Android, and Windows Mobile users. The consumer edition for iOS and Android, BBM Consumer, was developed by Indonesian company Emtek under licence from BlackBerry Limited (formerly known as Research In Motion). The consumer edition for BlackBerry OS and BlackBerry 10, as well as the paid enterprise edition, called BBM Enterprise (BBMe, formerly known as BBM Protected), were developed fully by BlackBerry Limited and continue to function. BBM Consumer for Android and iOS was shut down on 31 May 2019, however the paid enterprise version of the software, BBMe, is still supported on these platforms. Messages sent via BBM were sent over the Internet and used the BlackBerry PIN system. In the past, many service providers allowed sign-in to BBM using a dedicated BlackBerry data plan. Exchanging messages was possible to a single person or via dedicated discussion or chat groups, which allowed multiple BlackBerry devices to communicate in a single session. In addition to offering text-based instant messages, BBM also allowed users to send pictures, voicenotes (audio recordings), files (up to 16 MB), share real time location on a map, stickers and a wide selection of emojis. Communication was possible only among BlackBerry devices, until late 2013 when BBM was released on iOS and Android systems. Over 300 million Stickers were shared. Daily, approximately 150,000 BBM Voice Calls were placed. There were more than 190 million BBM users worldwide as of 2015, and BlackBerry infrastructure handled 30 petabytes of data traffic each month by early 2013. BBM was the original "mobile-first" messaging service, and was popular for a while before it started to lose out to rivals. As of April 2016, Indonesia was the only country where BBM was the most popular messaging app – installed on 87.5% of Android devices in the country.

Global Leadership
Global Leadership is the interdisciplinary study of the key elements that future leaders in all realms of the personal experience should acquire to effectively familiarize themselves with the psychological, physiological, geographical, geopolitical, anthropological and sociological effects of globalization. Global leadership occurs when an individual or individuals navigate collaborative efforts of different stakeholders through environmental complexity towards a vision by leveraging a global mindset. Today, global leaders must be capable of connecting "people across countries and engage them to global team collaboration in order to facilitate complex processes of knowledge sharing across the globe" As a result of trends, starting with colonialism and perpetuated by the increase in mass media, innovation, (brought about by the Internet and other forms of human interaction based on the speed of computer-mediation) a host of meaningful new concerns face mankind; consisting of but not limited to: human enterprises toward peace, international business design, and significant shifts in geopolitical paradigms. The talent and insight it will take leaders to successfully navigate humanity through these developments have been collectively focused around the phenomenon of globalization in order to embrace and effectively guide the evolution of mankind through the continued blurring and integration of national, economic and social strategies .

Misogyny in Horror Films
Misogyny can occur in horror films when there is a degrading representation of women. This is found particularly in slasher films, where there is often gendered specific violence towards women. Female characters experience violence and brutality at the hands of male antagonists far more often than male characters in these films. Female characters are likely to experience sexual violence, particularly in the rape-and-revenge subgenre.

Relative Direction
The most common relative directions are left, right, forward(s), backward(s), up, and down. No absolute direction corresponds to any of the relative directions. This is a consequence of the translational invariance of the laws of physics: nature, loosely speaking, behaves the same no matter what direction one moves. As demonstrated by the Michelson-Morley null result, there is no absolute inertial frame of reference. There are definite relationships between the relative directions, however. Left and right, forward and backward, and up and down are three pairs of complementary directions, each pair orthogonal to both of the others. Relative directions are also known as egocentric coordinates.

Trauma Quality Improvement Program
The Trauma Quality Improvement Program (TQIP) was initiated in 2008 by the American College of Surgeons Committee on Trauma. Its aim is to provide risk-adjusted data for the purpose of reducing variability in adult trauma outcomes and offering best practice guidelines to improve trauma care. TQIP makes use of national data to allows hospitals to objectively evaluate their trauma centers’ performance relative to other hospitals. TQIP’s administrative costs are less than those of other programs, making it an accessible tool for assessing performance and enhancing quality of trauma care.

Ghazal
The ghazal (Bengali: গজল, Sylheti: ꠊꠏꠟ, Punjabi: ਗ਼ਜ਼ਲ, Urdu: غزَل , Hindi: ग़ज़ल, Persian: غزل‎, Azerbaijani: qəzəl, Turkish: gazel, Uzbek: gʻazal, Pashto: غزل‎, Template:Lang-gu,) is a form of amatory poem or ode, originating in Arabic poetry. A ghazal may be understood as a poetic expression of both the pain of loss or separation and the beauty of love in spite of that pain. The ghazal form is ancient, tracing its origins to 7th-century Arabic poetry. The ghazal spread into South Asia in the 12th century due to the influence of Sufi mystics and the courts of the new Islamic Sultanate, and is now most prominently a form of poetry of many languages of the Indian subcontinent and Turkey. A ghazal commonly consists of between five and fifteen couplets, which are independent, but are linked – abstractly, in their theme; and more strictly in their poetic form. The structural requirements of the ghazal are similar in stringency to those of the Petrarchan sonnet. In style and content, due to its highly allusive nature, the ghazal has proved capable of an extraordinary variety of expression around its central themes of love and separation.
