2021 Columbia University Strike
The 2021 Columbia University strike was a labor strike involving graduate students at Columbia University in New York City . The strike, which began on March 15, 2021, was organized by the Graduate Workers of Columbia–United Auto Workers Local 2110, a labor union representing student workers at the university. This union was formed in December 2016 and has had a contentious relationship with the university since its founding, with the university only agreeing to recognize the union in 2019. That same year, the union and university began to negotiate a labor contract, but disagreements between the two entities have prevented an agreement from being made. The main issue concerns union recognition, with the university recognizing only fully-funded doctoral students as union members, while the union also recognizes master's students and undergraduate teaching assistants as members. Additional issues include disagreements over health benefits and child care, among others. While the union voted in March 2020 to authorize strike action, these plans were postponed due to the COVID-19 pandemic. However, in February 2021, still without a labor contract, the union announced their intent to strike the following month. The strike began on March 15 as an open-ended strike action, with no set end date. The strike coincided with a tuition strike that had been coordinated by the local chapter of the Young Democratic Socialists of America. Picketing and other forms of protest were held at numerous Columbia locations throughout New York City, and multiple elected officials and politicians announced their support for the strikers. On April 19, a contract proposal was submitted for ratification by the union members, but it was rejected in a rank-and-file vote. Following this, a vote was held in early May to determine the future of the strike, with a majority of voters choosing to end the strike, which officially ended on May 13. Following the end of the strike, on July 3, new leaders for the union were elected who promised to continue to push for a labor contract with the university. Additionally, the name of the union was changed to the Student Workers of Columbia. While negotiations were set to resume on August 25, a disagreement between who should be allowed to attend the meeting caused an impasse, with Columbia pushing for a closed-door meeting with a limited number of attendees and the union wanting the negotiations open to all members. On September 15, the union initiated another strike authorization vote and filed an unfair labor practice charge against the university.

Vidya
Vidya (Sanskrit: विद्या, IAST: vidyā) figures prominently in all texts pertaining to Indian philosophy – meaning science, learning, knowledge, and scholarship. Most importantly, it refers to valid knowledge, which cannot be contradicted, and true knowledge, which is the intuitively-gained knowledge of the self. Vidya is not mere intellectual knowledge, for the Vedas demand understanding.

Social Learning Tools
Social learning tools are tools used for pedagogical and andragogical purposes that utilize social software and/or social media in order to facilitate learning through interactions between individuals and systems. The idea of setting up "social learning tools" is to make education more convenient and widespread. It also allows an interaction between users and/or the software which can bring a different aspect to learning. People can acquire knowledge by distance learning tools, for instance, Facebook, Twitter, Khan Academy and so on. Social learning tools may mediate in formal or informal learning environments to help create connections between learners, instructors and information. These connections form dynamic knowledge networks. Social learning tools are used in schools for teaching/learning and in businesses for training. Within a school environment, the use of social learning tools can affect not only the user (student) but his/her caretaker as well as his/her instructor. It brings a different approach to the traditional way of learning which affects the student and his/her support circle. Companies also use social learning tools. They used them to improve knowledge transfer within departments and across teams. Businesses use a variety of these tools to create a social learning environment. They are also used in company settings to help improve team work, problem solving, and performance in stressful situations. Social learning tools are used for people who are willing to share their good ideas/thoughts with someone else. The ideas can be related to either the academic studies or any other daily skills that we want to share with others. Social learning tools connect learning to our daily lives. It creates a learning environment more truthful to today's society. There are a couple of common elements that should be present in a social learning tool. Technology should be involved to allow physical and cognitive learning. There should be interactions between the people who use the tool and interactions with the software. Another element is trust. Users should trust the software and what other people have created.

Huītzilōpōchtli
In Aztec mythology, Huitzilopochtli (Template:Lang-nci-IPA, modern Nahuatl pronunciation (help·info)) is the deity of war, sun, human sacrifice, and the patron of the city of Tenochtitlan. He was also the tribal god of the Mexicas, also known as the Aztecs, of Tenochtitlan. Many in the pantheon of deities of the Aztecs were inclined to have a fondness for a particular aspect of warfare. However, Huitzilopochtli was known as the primary god of war in ancient Mexico. Since he was the patron god of the Mexica, he was credited with both the victories and defeats that the Mexica people had on the battlefield. The people had to make sacrifices to him to protect the Aztec from infinite night. He wielded Xiuhcoatl, the fire serpent, as a weapon, thus also associating Huitzilopochtli with fire. As noted by the Spaniards during their discovery and conquest of the Aztec Empire (wherein they recorded the deity's name as Huichilobos), human sacrifice was common in worship ceremonies, which took place frequently and in numerous temples throughout the region, and when performed they typically sacrificed multiple victims per day at a given temple.

Internal Monologue
An internal monologue, also called self-talk, inner speech, inner discourse or internal discourse, is a person's inner voice which provides a running verbal monologue of thoughts while they are conscious. It is usually tied to a person's sense of self. It is particularly important in planning, problem solving, self-reflection, self-image, critical thinking, emotions, and subvocalization (reading in one's head). As a result, it is relevant to a number of mental disorders, such as depression, and treatments like cognitive behavioural therapy which seek to alleviate symptoms by providing strategies to regulate cognitive behaviour. It may reflect both conscious and subconscious beliefs. In some cases people may think of inner speech as coming from an external source, as with schizophrenic auditory hallucinations. Additionally, not everyone has a verbal internal monologue (see § Absence of an internal monologue). The looser flow of thoughts and experiences, verbal or not, is called a stream of consciousness, which can also refer to a related technique in literature. In a theory of child development formulated by Lev Vygotsky, inner speech has a precursor in private speech (talking to oneself) at a young age.

Last Mile
The last mile or last kilometer is a phrase widely used in the telecommunications, cable television and internet industries to refer to the final leg of the telecommunications networks that deliver telecommunication services to retail end-users (customers). More specifically, the last mile describes the portion of the telecommunications network chain that physically reaches the end-user's premises. Examples are the copper wire subscriber lines connecting landline telephones to the local telephone exchange; coaxial cable service drops carrying cable television signals from utility poles to subscribers' homes, and cell towers linking local cell phones to the cellular network. The word "mile" is used metaphorically; the length of the last mile link may be more or less than a mile. Because the last mile of a network to the user is conversely the first mile from the user's premises to the outside world when the user is sending data, the term first mile is also alternatively used. The last mile is typically the speed bottleneck in communication networks; its bandwidth effectively limits the amount of data that can be delivered to the customer. This is because retail telecommunication networks have the topology of "trees", with relatively few high capacity "trunk" communication channels branching out to feed many final mile "twigs". The final mile links, being the most numerous and thus the most expensive part of the system, as well as having to interface with a wide variety of user equipment, are the most difficult to upgrade to new technology. For example, telephone trunklines that carry phone calls between switching centers are made of modern optical fiber, but the last mile is typically twisted pair wires, a technology which has essentially remained unchanged for over a century since the original laying of copper phone cables. To resolve, or at least mitigate, the problems involved with attempting to provide enhanced services over the last mile, some firms have been mixing networks for decades. One example is fixed wireless access, where a wireless network is used instead of wires to connect a stationary terminal to the wireline network. Various solutions are being developed which are seen as an alternative to the last mile of standard incumbent local exchange carriers. These include WiMAX and broadband over power lines. In recent years, usage of the term "last mile" has expanded outside the communications industries, to include other distribution networks that deliver goods to customers, such as the pipes that deliver water and natural gas to customer premises, and the final legs of mail and package delivery services. The term has also been used to describe education and training providers that more tightly link individuals with job opportunities.

Ratooning
Ratooning is the agricultural practice of harvesting a monocot crop by cutting most of the above-ground portion but leaving the roots and the growing shoot apices intact so as to allow the plants to recover and produce a fresh crop in the next season. This practice is widely used in the cultivation of crops such as rice, sugarcane, banana, and pineapple. Ratoon crops cannot be perennially renewed, and may be harvested only for a few seasons, as a decline in yield tends to occur due to increased crowding, damage by pests and diseases, and decreasing soil fertility.
