Compassion fatigue is a condition characterized by emotional and physical exhaustion leading to a diminished ability to empathize or feel compassion for others, often described as the negative cost of caring. It is sometimes referred to as secondary traumatic stress (STS). According to the Professional Quality of Life Scale, burnout and secondary traumatic stress are two interwoven elements of compassion fatigue.

Compassion fatigue is considered to be the result of working directly with victims of disasters, trauma, or illness, especially in the health care industry. Individuals working in other helping professions are also at risk for experiencing compassion fatigue. These include child protection workers, veterinarians, teachers, social workers, palliative care workers, journalists, police officers, firefighters, animal welfare workers, public librarians, health unit coordinators, and Student Affairs professionals. Non-professionals, such as family members and other informal caregivers of people who have a chronic illness, may also experience compassion fatigue. The term was first coined in 1992 by Carla Joinson to describe the negative impact hospital nurses were experiencing as a result of their repeated, daily exposure to patient emergencies.

People who experience compassion fatigue may exhibit a variety of symptoms including lowered concentration, numbness or feelings of helplessness, irritability, lack of self-satisfaction, withdrawal, aches and pains, or work absenteeism.

Journalism analysts argue that news media have caused widespread compassion fatigue in society by saturating newspapers and news shows with decontextualized images and stories of tragedy and suffering. This has caused the public to become desensitized or resistant to helping people who are suffering.

In mathematics, the Menger sponge (also known as the Menger cube, Menger universal curve, Sierpinski cube, or Sierpinski sponge) is a fractal curve. It is a three-dimensional generalization of the one-dimensional Cantor set and two-dimensional Sierpinski carpet. It was first described by Karl Menger in 1926, in his studies of the concept of topological dimension.

The Alcoa 50,000 ton forging press is a heavy press operated at Howmet Aerospace's Cleveland Operations. It was built as part of the Heavy Press Program by the United States Air Force. It was manufactured by Mesta Machinery of West Homestead, Pennsylvania, and began operation on May 5, 1955.

Alcoa ran the plant from the time of its construction, and purchased it outright in 1982. In 2008, cracks were discovered in the press, which had to be shut down for safety reasons. Repairs, originally estimated at a cost of $68 million (equivalent to $81.04 million in 2019), cost a total of $100 million, and were completed in early 2012.

Euro English or European English, less commonly known as EU English and EU Speak, is a pidgin dialect of English based on the technical jargon of the European Union and the native languages of its non-native English speaking population. It is mostly used among EU staff, expatriates from EU countries, young international travellers (such as exchange students in the EU’s Erasmus programme), European diplomats, and sometimes by other Europeans that use English as a second or foreign language (especially Continental Europeans).

🔗 Health and fitness

Calisthenics (American English) or callisthenics (British English) is a form of exercise consisting of a variety of movements that exercise large muscle groups (gross motor movements), such as running, standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as bodyweight exercises. They are intended to increase strength, fitness, and flexibility, through movements such as pulling, pushing, bending, jumping, or swinging, using one's body weight for resistance. Calisthenics can provide the benefits of muscular and aerobic conditioning, in addition to improving psychomotor skills such as balance, agility, and coordination.

Urban calisthenics is a form of street workout; calisthenics groups perform exercise routines in urban areas. Individuals and groups train to perform advanced calisthenics skills such as muscle-ups, levers, and various freestyle moves such as spins and flips.

Sports teams and military units often perform leader-directed group calisthenics as a form of synchronized physical training (often including a customized "call and response" routine) to increase group cohesion and discipline. Calisthenics is also popular as a component of physical education in primary and secondary schools over much of the globe.

In addition to general fitness, calisthenic exercises are often used as baseline physical evaluations for military organizations around the world. Two examples are the U.S. Army Physical Fitness Test and the U.S.M.C. Physical Fitness Test.

The Kearny fallout meter, or KFM, is an expedient radiation meter. It is designed such that someone with a normal mechanical ability would be able to construct it before or during a nuclear attack, using common household items.

The Kearny fallout meter was developed by Cresson Kearny from research performed at Oak Ridge National Laboratory and published in the civil defense manual Nuclear War Survival Skills (ISBN 0-942487-01-X). The plans were originally released in Oak Ridge National Laboratory publication ORNL-5040, The KFM, A Homemade Yet Accurate and Dependable Fallout Meter and have been formatted in a newsprint-ready layout so that they may be quickly printed with accurate dimensions in local newspapers. It must be built from a correctly scaled copy of the plans; photocopies and printouts of digital copies may not be to scale.

🔗 United States 🔗 Politics 🔗 Elections and Referendums

In American political jargon, an October surprise is a news event deliberately created or timed to influence the outcome of an election, particularly one for the U.S. presidency, or sometimes an event occurring spontaneously that has the same effect. Because the date for national elections (as well as many state and local elections) is in early November, events that take place in October have greater potential to influence the decisions of prospective voters. Thus these relatively last-minute news stories could either completely change the entire course of an election or strongly reinforce the inevitable.

The term "October surprise" was coined by William Casey when he served as campaign manager of Ronald Reagan's 1980 presidential campaign. However, there were October election-upending events that predated the coining of the term.

Aristotle's views on women influenced later Western thinkers, as well as Islamic thinkers, who quoted him as an authority until the end of the Middle Ages, influencing women's history.

In his Politics, Aristotle saw women as subject to men, but as higher than slaves, and lacking authority; he believed the husband should exert political rule over the wife. Among women's differences from men were that they were, in his view, more impulsive, more compassionate, more complaining, and more deceptive. He gave the same weight to women's happiness as to men's, and in his Rhetoric stated that society could not be happy unless women were happy too. Whereas Plato was open to the potential equality of men and women, stating both that women were not equal to men in terms of strength and virtue, but were equal to men in terms of rational and occupational capacity, and hence in the ideal Republic should be educated and allowed to work alongside men without differentiation, Aristotle appears to have disagreed.

In his theory of inheritance, Aristotle considered the mother to provide a passive material element to the child, while the father provided an active, ensouling element with the form of the human species.

🔗 Computing 🔗 Microsoft Windows 🔗 Microsoft Windows/Computing

The AARD code was a segment of code in a beta release of Microsoft Windows 3.1 that would determine whether Windows was running on MS-DOS or PC DOS, rather than a competing workalike such as DR-DOS, and would result in a cryptic error message in the latter case. This XOR-encrypted, self-modifying, and deliberately obfuscated machine code used a variety of undocumented DOS structures and functions to perform its work, and appeared in the installer, WIN.COM, and several other executables in the OS.

The AARD code was originally discovered by Geoff Chappell on 17 April 1992 and then further analyzed and documented in a joint effort with Andrew Schulman. The name was derived from Microsoft programmer Aaron R. Reynolds (1955–2008), who used "AARD" to sign his work; "AARD" was found in the machine code of the installer. Microsoft disabled the AARD code for the final release of Windows 3.1, but did not remove it, so that it could have become reactivated later by the change of a single byte in an installed system, thereby constituting a "smoking gun".

DR-DOS publisher Digital Research released a patch named "business update" in 1992 to enable the AARD tests to pass on its operating system.

The rationale for the AARD code came to light when internal memos were released during the United States v. Microsoft Corp. antitrust case in 1999. Internal memos released by Microsoft revealed that the specific focus of these tests was DR-DOS. At one point, Microsoft CEO Bill Gates sent a memo to a number of employees, reading "You never sent me a response on the question of what things an app would do that would make it run with MS-DOS and not run with DR-DOS. Is there [sic] feature they have that might get in our way?" Microsoft Senior Vice President Brad Silverberg later sent another memo, stating: "What the [user] is supposed to do is feel uncomfortable, and when he has bugs, suspect that the problem is DR-DOS and then go out to buy MS-DOS."

Following the purchase of DR-DOS by Novell and its renaming to "Novell DOS", Microsoft Co-President Jim Allchin stated in a memo, "If you're going to kill someone there isn't much reason to get all worked up about it and angry. Any discussions beforehand are a waste of time. We need to smile at Novell while we pull the trigger."

What had been DR-DOS changed hands again. The new owner, Caldera, Inc., began a lawsuit against Microsoft over the AARD code, Caldera v. Microsoft, which was later settled. It was believed that the settlement ran in the order of $150 million, but was revealed in November 2009 with the release of the Settlement Agreement to be $280 million.

🔗 China 🔗 Writing systems

Since the second half of the 20th century, inscriptions have been found on pottery in a variety of locations in China, such as Banpo near Xi'an, as well as on bone and bone marrows at Hualouzi, Chang'an County near Xi'an. These simple, often geometric, marks have been frequently compared to some of the earliest known Chinese characters appearing on the oracle bones, and some have taken them to mean that the history of Chinese writing extends back over six millennia. However, only isolated instances of these symbols have been found, and they show no indication of representing speech or of the non-pictorial processes that a writing system requires.
