Economic Impact Analysis
An economic impact analysis (EIA) examines the effect of an event on the economy in a specified area, ranging from a single neighborhood to the entire globe. It usually measures changes in business revenue, business profits, personal wages, and/or jobs. The economic event analyzed can include implementation of a new policy or project, or may simply be the presence of a business or organization. An economic impact analysis is commonly conducted when there is public concern about the potential impacts of a proposed project or policy. An economic impact analysis typically measures or estimates the change in economic activity between two scenarios, one assuming the economic event occurs, and one assuming it does not occur (which is referred to as the counterfactual case). This can be accomplished either before or after the event (ex ante or ex post). An economic impact analysis attempts to measure or estimate the change in economic activity in a specified region, caused by a specific business, organization, policy, program, project, activity, or other economic event. The study region can be a neighborhood, town, city, county, statistical area, state, country, continent, or the entire globe.

Runoff Model (Reservoir)
A runoff model is a mathematical model describing the rainfall–runoff relations of a rainfall catchment area, drainage basin or watershed. More precisely, it produces a surface runoff hydrograph in response to a rainfall event, represented by and input as a hyetograph. In other words, the model calculates the conversion of rainfall into runoff. A well known runoff model is the linear reservoir, but in practice it has limited applicability. The runoff model with a non-linear reservoir is more universally applicable, but still it holds only for catchments whose surface area is limited by the condition that the rainfall can be considered more or less uniformly distributed over the area. The maximum size of the watershed then depends on the rainfall characteristics of the region. When the study area is too large, it can be divided into sub-catchments and the various runoff hydrographs may be combined using flood routing techniques. Rainfall-runoff models need to be calibrated before they can be used.

Zoom
Zoom Meetings (commonly shortened to Zoom, and stylized as zoom) is a proprietary videotelephony software program developed by Zoom Video Communications. The free plan allows up to 100 concurrent participants, with a 40-minute time restriction. Users have the option to upgrade by subscribing to a paid plan. The highest plan supports up to 1,000 concurrent participants for meetings lasting up to 30 hours. During the COVID-19 pandemic, there was a major increase in the use of Zoom for remote work, distance education, and online social relations. The increase led to Zoom being one of the most downloaded mobile app worldwide in 2020 with over 500 million downloads. In 2020 Zoom had over 300 million daily meeting participants.

Ocean Biogeographic Information System
The Ocean Biogeographic Information System (OBIS) is a web-based access point to information about the distribution and abundance of living species in the ocean. It was developed as the information management component of the ten year Census of Marine Life (CoML) (2001-2010), but is not limited to CoML-derived data, and aims to provide an integrated view of all marine biodiversity data that may be made available to it on an open access basis by respective data custodians. According to its web site as at July 2018, OBIS "is a global open-access data and information clearing-house on marine biodiversity for science, conservation and sustainable development." 8 specific objectives are listed in the OBIS site, of which the leading item is to "Provide [the] world's largest scientific knowledge base on the diversity, distribution and abundance of all marine organisms in an integrated and standardized format".

Comprehensive School Mathematics Program
Comprehensive School Mathematics Program (CSMP) stands for both the name of a curriculum and the name of the project that was responsible for developing curriculum materials in the United States. Two major curricula were developed as part of the overall CSMP project: the Comprehensive School Mathematics Program (CSMP), a K–6 mathematics program for regular classroom instruction, and the Elements of Mathematics (EM) program, a grades 7–12 mathematics program for gifted students. EM treats traditional topics rigorously and in-depth, and was the only curriculum that strictly adhered to Goals for School Mathematics: The Report of the Cambridge Conference on School Mathematics (1963). As a result, it includes much of the content generally required for an undergraduate mathematics major. These two curricula are unrelated to one another, but certain members of the CSMP staff contributed to the development of both projects. Additionally, some staff were involved with the Secondary School Mathematics Curriculum Improvement Study program being developed around the same time. What follows is a description of the K–6 program that was designed for a general, heterogeneous audience. The CSMP project was established in 1966, under the direction of Burt Kaufman, who remained director until 1979, succeeded by Clare Heidema. It was originally affiliated with Southern Illinois University in Carbondale, Illinois. After a year of planning, CSMP was incorporated into the Central Midwest Regional Educational Laboratory (later CEMREL, Inc.), one of the national educational laboratories funded at that time by the U.S. Office of Education. In 1984, the project moved to Mid-continental Research for Learning (McREL) Institute's Comprehensive School Reform program, who supported the program until 2003. Heidema remained director to its conclusion. In 1984, it was implemented in 150 school districts in 42 states and about 55,000 students.

Comparison Between Esperanto and Interlingua
Esperanto and Interlingua are two planned languages which have taken radically different approaches to the problem of providing an International auxiliary language (IAL). Although they are both classed as IALs, the intellectual bases of Esperanto and Interlingua are quite different. It has been argued that each language is a successful implementation of a particular IAL model. However, in both language communities there is a polemical tradition of using external criteria to critique the perceived opponent language (that is, judging Interlingua by Esperantist criteria and vice versa). In practical use, moreover, language usage in the two communities has sometimes shown convergences despite divergent theory.

DNS Zone Transfer
DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers. A zone transfer uses the Transmission Control Protocol (TCP) for transport, and takes the form of a client–server transaction. The client requesting a zone transfer may be a secondary server requesting data from a primary server, historically referred to as master and slave. The portion of the database that is replicated is a zone.
