Claire Kelly Schultz
Claire Kelly Schultz (November 17, 1924 - May 28, 2015) was a leading figure in the early development of automated information retrieval systems and information science. A "documentalist", she was particularly known for her work in thesaurus construction and machine-aided indexing, innovating techniques for punch card information retrieval. While working as a librarian at the Merck, Sharp and Dohme chemical company she "developed a machine-sorted card system that employed Boolean retrieval logic. Her first use of punched cards in 1949 used the Mooers Zator system."Williams, Robert V. "The use of punched cards in US libraries and documentation centers, 1936-1965." IEEE Annals of the History of Computing 2 (2002): 16-33. This has been seen as a "transitional role of such punched-card systems toward later use of computers for information retrieval".Henderson, Madeline M. "Examples of early nonconventional technical information systems." Science Information Systems (1999): 169-176, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etters, Pennsylvania
Goldsboro (formerly Goldsborough) is a Borough (Pennsylvania), borough in York County, Pennsylvania, York County, Pennsylvania, United States. The population was 930 at the 2020 United States census, 2020 census. For historical reasons, the post office in Goldsboro is named "Etters", although there is no incorporated place known by that name, and the United States Postal Service (USPS) states that the name "Etters" is preferred over "Goldsboro" for addressing mail to ZIP code 17319. History In 1738 Nathan Hussey, a Quaker, from New Castle County, Delaware, obtained a grant for land on which the Village of Goldsboro now stands. In 1743 a road from Walnut Bottom, now in Cumberland County, to Hussey's ferry was built. The turnpike was completed in 1816 from York to Harrisburg. Along the turnpike, near the site of Hussey's Ferry (now Middletown Ferry) Henry Etter established Etter's Tavern, which included Etter's Post Office by 1838. Goldsboro was founded in 1850 upon completion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Research Council (United States)
The National Academies of Sciences, Engineering, and Medicine (also known as NASEM or the National Academies) are the collective scientific national academy of the United States. The name is used interchangeably in two senses: (1) as an umbrella term for its three quasi-independent honorific member organizations the National Academy of Sciences (NAS), the National Academy of Engineering (NAE), and the National Academy of Medicine (NAM); and (2) as the brand for studies and reports issued by the operating arm of the three academies, the National Research Council (NRC). The NRC was first formed in 1916 as an activity of the NAS. Now jointly governed by all three academies, the NRC produces some 200 publications annually which are published by the National Academies Press. The reports produced by the National Academies have been characterized as reflective of scientific consensus.

Census Bureau
The United States Census Bureau (USCB), officially the Bureau of the Census, is a principal agency of the U.S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureau is part of the U.S. Department of Commerce and its director is appointed by the President of the United States. The Census Bureau's primary mission is conducting the U.S. census every ten years, which allocates the seats of the U.S. House of Representatives to the states based on their population. The bureau's various censuses and surveys help allocate over $675 billion in federal funds every year and it assists states, local communities, and businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, hospitals, transportation infrastructure, and police and fire departments. In addition to the decennial census, the Census Bureau continually conducts over 130 surveys and programs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 101
The IBM 101 Electronic Statistical Machine, introduced in 1952, combines in one unit the functions of sorting, counting, accumulating, balancing, editing, and printing of summaries of facts recorded in IBM cards. The 101 could sort cards based on multiple columns. For example, if a card had multiple 3-column test scores, the 101 could be wired to sort into pocket 0 those cards with no scores over 090, into pocket 1 those with one score over 090, and so on; logic limited only by the number of relays available. A. Ross Eckler suggests the development of the 101, with functions similar to earlier multicolumn sorters and unit counters developed by the Census Bureau, "was apparently a direct result of the transfer to IBM of Lawrence Wilson, who had served as chief of the Census Bureau's Machine Tabulation Division". Functions The following operations may be performed at the rate of 450 cards per minute: * Sort IBM cards into numeric or alphabetic sequence * Arrange cards into a desi ...

Boolean Logic
In mathematics and mathematical logic, Boolean algebra is a branch of algebra. It differs from elementary algebra in two ways. First, the values of the variable (mathematics), variables are the truth values ''true'' and ''false'', usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers. Second, Boolean algebra uses Logical connective, logical operators such as Logical conjunction, conjunction (''and'') denoted as ∧, Logical disjunction, disjunction (''or'') denoted as ∨, and the negation (''not'') denoted as ¬. Elementary algebra, on the other hand, uses arithmetic operators such as addition, multiplication, subtraction and division. So Boolean algebra is a formal way of describing logical operations, in the same way that elementary algebra describes numerical operations. Boolean algebra was introduced by George Boole in his first book ''The Mathematical Analysis of Logic'' (1847), and set forth more fully in his ''The Laws of Thought, ...

Calvin Mooers
Calvin Northrup Mooers (October 24, 1919 – December 1, 1994), was an American computer scientist known for his work in information retrieval and for the programming language TRAC. Early life Mooers was a native of Minneapolis, Minnesota, attended the University of Minnesota, and received a bachelor's degree in mathematics in 1941. He worked at the Naval Ordnance Laboratory from 1941 to 1946, and then attended the Massachusetts Institute of Technology, where he earned a master's degree in mathematics and physics. At M.I.T. he developed a mechanical system using superimposed codes of descriptors for information retrieval called Zatocoding. He founded the Zator Company in 1947 to market this idea, and pursued work in information theory, information retrieval, and artificial intelligence. He coined the term "information retrieval", using it first in a conference paper presented in March 1950. See also a short paper published later that year from Mooers. Mooers's law He coined ...

Fertility
Fertility is the capability to produce offspring through reproduction following the onset of sexual maturity. The fertility rate is the average number of children born by a female during her lifetime and is quantified demographically. Fertility is addressed when there is a difficulty or an inability to reproduce naturally, which is referred to as infertility. Infertility is widespread, with fertility specialists available all over the world to assist mothers and couples who experience difficulties having a baby. Human fertility depends on factors of nutrition, sexual behaviour, consanguinity, culture, instinct, endocrinology, timing, economics, personality, way of life, and emotions. Fertility differs from fecundity, which is defined as the ''potential'' for reproduction (influenced by gamete production, fertilization and carrying a pregnancy to term). Where a woman or the lack of fertility is infertility while a lack of fecundity would be called sterility. Demography I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
