Spectra (mathematical Association)
Spectra is a professional association of LGBTQIA+ mathematicians. It arose from a need for recognition and community for Gender and Sexual Minority mathematicians. History Spectra has its roots in meetups arranged at the Joint Mathematics Meetings (JMM) and a mailing list organized by Ron Buckmire. It arose in reaction to the JMM being scheduled to occur in Denver in 1995 when the state of Colorado voters approved the anti-gay 1992 Colorado Amendment 2. The association's name was coined by Robert Bryant and Mike Hill and references the mathematical concept of a spectrum as well as the rainbow flag. Its first official activity was a panel at the 2015 JMM with the title "Out in Mathematics: LGBTQ Mathematicians in the Workplace." Out and Ally Lists Spectra maintains a list of mathematicians who are out in the LGBTQIA+ community as well as a list of allies for the community. The goal of the list is to serve as support for mathematicians at various places on their own LGBTQ+ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LGBT
' is an initialism that stands for lesbian, gay, bisexual, and transgender. In use since the 1990s, the initialism, as well as some of its common variants, functions as an umbrella term for sexuality and gender identity. The LGBT term is an adaptation of the initialism ', which began to replace the term ''gay'' (or ''gay and lesbian'') in reference to the broader LGBT community beginning in the mid-to-late 1980s. When not inclusive of transgender people, the shorter term LGB is still used instead of LGBT. It may refer to anyone who is non-heterosexual or non- cisgender, instead of exclusively to people who are lesbian, gay, bisexual, or transgender. To recognize this inclusion, a popular variant, ', adds the letter ''Q'' for those who identify as queer or are questioning their sexual or gender identity. The initialisms ''LGBT'' or ''GLBT'' are not agreed to by everyone that they are supposed to include. History of the term The first widely used term, '' homose ...

Coming Out
Coming out of the closet, often shortened to coming out, is a metaphor used to describe LGBT people's self-disclosure of their sexual orientation, romantic orientation, or gender identity. Framed and debated as a privacy issue, coming out of the closet is experienced variously as a psychological process or journey; decision-making or risk-taking; a strategy or plan; a mass or public event; a speech act and a matter of personal identity; a rite of passage; liberation or emancipation from oppression; an ordeal; a means toward feeling gay pride instead of shame and social stigma; or even a career-threatening act. Author Steven Seidman writes that "it is the power of the closet to shape the core of an individual's life that has made homosexuality into a significant personal, social, and political drama in twentieth-century America". ''Coming out of the closet'' is the source of other gay slang expressions related to voluntary disclosure or lack thereof. LGBT people who ...

Mathematical Societies
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Professional Associations Based In The United States
A professional is a member of a profession or any person who works in a specified professional activity. The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform their specific role within that profession. In addition, most professionals are subject to strict codes of conduct, enshrining rigorous ethical and moral obligations. Professional standards of practice and ethics for a particular field are typically agreed upon and maintained through widely recognized professional associations, such as the IEEE. Some definitions of "professional" limit this term to those professions that serve some important aspect of public interest and the general good of society.Sullivan, William M. (2nd ed. 2005).

Straight Ally
An ally is a person who is associated with another as a helper; a person or group that provides assistance and support in an ongoing effort, activity or struggle. In recent years, the term has been adopted specifically to a person supporting one or more marginalized groups. A straight ally or heterosexual ally (often simply called an ally) is a heterosexual and cisgender person who supports equal civil rights, gender equality, and LGBTQ+ social movements. Individuals may meet this designation through their actions without actively identifying as an ally. In February 2012, American writer David M. Hall wrote an article for CNN, about the television show Glee, in which he expressed the following opinion: A straight ally aims to use their position of privilege as cisgender or heterosexual people in a society biased towards heteronormativity to bring down the inequalities of transphobia, biphobia, and homophobia. "Without straight allies, the queer rights movement would not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Flag (LGBT Movement)
The rainbow flag, also known as the (gay) pride flag, is a symbol of lesbian, gay, bisexual, and transgender (LGBT) pride and LGBT social movements. The colors reflect the diversity of the LGBT community and the spectrum of human sexuality and gender. Using a rainbow flag as a symbol of gay pride began in San Francisco, California, but eventually became common at LGBT rights by country or territory, LGBT rights events worldwide. Originally devised by artist Gilbert Baker (artist), Gilbert Baker, Lynn Segerblom, James McNamara and other activists, the design underwent several revisions after its debut in 1978, and continues to inspire variations. Although Baker's original rainbow flag had eight colors, from 1979 to the present day the most common variant consists of six stripes: red, orange, yellow, green, blue, and violet. The flag is typically displayed horizontally, with the red stripe on top, as it would be in a natural rainbow. LGBT people and straight ally, allies curren ...

Joint Mathematics Meetings
The Joint Mathematics Meetings (JMM) is a mathematics conference hosted annually in early January by the American Mathematical Society (AMS). Frequently, several other national mathematics organizations also participate. The meeting is the largest gathering of mathematicians in the United States, and the largest annual meeting of mathematicians in the world. For example, more than 6000 people attended the 2017 JMM. Several thousand talks, panels, minicourses, and poster sessions are held each year. The JMM also hosts an ''Employment Center'', which is a focal point for the hiring process of academic mathematicians, especially for liberal arts colleges. Many employers conduct their preliminary interview process at the meeting. Often these interviews take place outside the confines of the conference, so the employers may not appear on the official Employment Center listing.

Spectrum Of A Matrix
In mathematics, the spectrum of a matrix is the set of its eigenvalues. More generally, if T\colon V \to V is a linear operator on any finite-dimensional vector space, its spectrum is the set of scalars \lambda such that T-\lambda I is not invertible. The determinant of the matrix equals the product of its eigenvalues. Similarly, the trace of the matrix equals the sum of its eigenvalues. From this point of view, we can define the pseudo-determinant for a singular matrix to be the product of its nonzero eigenvalues (the density of multivariate normal distribution will need this quantity). In many applications, such as PageRank, one is interested in the dominant eigenvalue, i.e. that which is largest in absolute value. In other applications, the smallest eigenvalue is important, but in general, the whole spectrum provides valuable information about a matrix. Definition Let ''V'' be a finite-dimensional vector space over some field ''K'' and suppose ''T'' : ''V'' → ''V'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
