California Coalition For Immigration Reform
California Coalition for Immigration Reform (CCIR) was a Huntington Beach, California-based political advocacy group devoted to immigration reduction, with an emphasis on combating illegal immigration to the United States. According to the organization's website, its objectives were to "promote and expand citizen and legal resident awareness by a practical, effective communication network" and to "mobilize citizens and legal residents to support elected representatives and legislation" who favor immigration reduction. After the 2013 death of its original leader, Barbara Coe, the group renamed itself the National Council for Issue Reform.National Council for Issue Reform , |
Campaign For Comprehensive Immigration Reform
The Coalition for Comprehensive Immigration Reform (CCIR), also known as CCIR/NAOC or New American Opportunity Campaign (NAOC), is a non-profit immigrant rights advocacy organization based in Washington, DC, established in 2003 to pass comprehensive immigration reform. It was instrumental in the 2004 Immigrant Workers Freedom Ride, modeled after the Freedom Rides of the Civil Rights Movement, and acts as an umbrella organization for several national and local immigrant rights organizations for advocacy and coalition building. The New American Opportunity Campaign was launched by CCIR in 2004. Soon, the campaign became the core project of the coalition, and NAOC became a better-known name than CCIR. CCIR consolidated its identity into the single "Coalition for Comprehensive Immigration Reform" name in 2007.

Canadian Centre For Investigative Reporting
Canadians () are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity and Canadian values. Canada has also been strongly influenced by its linguistic, geographic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comité Consultatif International Pour La Radio
The ITU Radiocommunication Sector (ITU-R) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU) and is responsible for radio communications. Its role is to manage the international radio-frequency spectrum and satellite orbit resources and to develop standards for radiocommunication systems with the objective of ensuring the effective use of the spectrum. ITU is required, according to its constitution, to allocate spectrum and register frequency allocation, orbital positions and other parameters of satellites, "in order to avoid harmful interference between radio stations of different countries". The international spectrum management system is therefore based on regulatory procedures for frequency coordination, notification and registration. ITU-R has a permanent secretariat, the Radiocommunication Bureau, based at the ITU HQ in Geneva, Switzerland. The elected Director of the Bureau is Mario Maniewicz; he was first elected ...

CCIR 601
ITU-R Recommendation BT.601, more commonly known by the abbreviations Rec. 601 or BT.601 (or its former name CCIR 601), is a standard originally issued in 1982 by the Comité consultatif international pour la radio, CCIR (an organization, which has since been renamed as the ITU-R, International Telecommunication Union Radiocommunication sector) for encoding Interlaced video, interlaced analog video signals in digital video form. It includes methods of encoding 525-line 60 Hertz, Hz and 625-line 50 Hz signals, both with an active region covering 720 Luma (video), luminance samples and 360 chrominance samples per line. The color encoding system is known as chroma subsampling#4:2:2, YCbCr 4:2:2. The Rec. 601 video raster format has been re-used in a number of later standards, including the ISO/IEC Moving Picture Experts Group, MPEG and ITU-T Video Coding Experts Group, H.26x compressed formats, although compressed formats for consumer applications usual ...

CCIR (selcall)
There are many types and formats of CCIR Selcall. For exampleCCIR 493-4is a standard format for HSelcallfor Land Mobile applications. CCIR (Consultative Committee on International Radio) functions have largely been taken over by ITU-R. One common type of CCIR selcall used in VHF and UHF FM two-way radio communications, is a 5-tone selective calling system mainly found in some European countries and used by the Swedish Police and the Turkish Police. The tone duration of a 5 tone CCIR selcall is 100 millisecond A millisecond (from '' milli-'' and second; symbol: ms) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10−3 or 1/1000) of a second or 1000 microseconds. A millisecond is to one second, as one second i ...s (± 10 ms) and the tones are transmitted sequentially. References * {{refend Radio technology Telephony signals ...

CCIR-1k
ITU-R 468 (originally defined in CCIR recommendation 468-4, therefore formerly also known as CCIR weighting; sometimes referred to as CCIR-1k) is a standard relating to noise measurement, widely used when measuring noise in audio systems. The standard, now referred to as ITU-R BS.468-4, defines a weighting filter curve, together with a quasi-peak rectifier having special characteristics as defined by specified tone-burst tests. It is currently maintained by the International Telecommunication Union who took it over from the CCIR. It is used especially in the UK, Europe, and former countries of the British Empire such as Australia and South Africa. It is less well known in the USA where A-weighting has always been used. M-weighting is a closely related filter, an offset version of the same curve, without the quasi-peak detector. Explanation The A-weighting curve was based on the 40 phon equal-loudness contour derived initially by Fletcher and Munson (1933). Originally inco ...
