full_context: Document 1: Communications in Somalia: Other radio stations based in Mogadishu include Mustaqbal Media corporation and the Shabelle Media Network, the latter of which was in 2010 awarded the Media of the Year prize by the Paris-based journalism organisation, Reporters Without Borders (RSF). In total, about one short-wave and ten private FM radio stations broadcast from the capital, with several radio stations broadcasting from the central and southern regions.
Document 2: Télérama: Télérama is a weekly French cultural and TV magazine published in Paris, France. The name is a contraction of its earlier title: Télévision-Radio-Cinéma. Fabienne Pascaud is currently editor in chief.
Document 3: Irana Esperantisto: Irana Esperantisto ("Iranian Esperantist") is an independent quarterly culture magazine, which is published in Esperanto and in Persian in Tehran and distributed internationally. Its Persian title is "Payame Sabz-andishan" (literally: Message of the Green-Thinkers or the Green-Adepts). About half of the content of each edition is in Esperanto and the other half in Persian.
Document 4: MP3: An in-depth study of MP3 audio quality, sound artist and composer Ryan Maguire's project "The Ghost in the MP3" isolates the sounds lost during MP3 compression. In 2015, he released the track "moDernisT" (an anagram of "Tom's Diner"), composed exclusively from the sounds deleted during MP3 compression of the song "Tom's Diner", the track originally used in the formulation of the MP3 standard. A detailed account of the techniques used to isolate the sounds deleted during MP3 compression, along with the conceptual motivation for the project, was published in the 2014 Proceedings of the International Computer Music Conference.
Document 5: Iranian languages: It is possible that other distinct dialect groups were already in existence during this period. Good candidates are the hypothethical ancestor languages of Alanian/Scytho-Sarmatian subgroup of Scythian in the far northwest; and the hypothetical "Old Parthian" (the Old Iranian ancestor of Parthian) in the near northwest, where original *dw > *b (paralleling the development of *ćw).
Document 6: Iranshenasi: Iran Shenasi also spelled as "Iranshinasi" () is an academic journal of Iranian studies. The founding editor-in-chief is Jalal Matini. The journal is published in Persian (with English abstracts) and covers Iranian history, Persian culture, and Persian literature.

The journal is a companion volume to "Leonardo", the journal of the International Society for the Arts, Sciences and Technology. The editor-in-chief is Roger Malina.
Document 10: Iranian languages: In addition to Old Persian and Avestan, which are the only directly attested Old Iranian languages, all Middle Iranian languages must have had a predecessor "Old Iranian" form of that language, and thus can all be said to have had an (at least hypothetical) "Old" form. Such hypothetical Old Iranian languages include Carduchi (the hypothetical predecessor to Kurdish) and Old Parthian. Additionally, the existence of unattested languages can sometimes be inferred from the impact they had on neighbouring languages. Such transfer is known to have occurred for Old Persian, which has (what is called) a "Median" substrate in some of its vocabulary. Also, foreign references to languages can also provide a hint to the existence of otherwise unattested languages, for example through toponyms/ethnonyms or in the recording of vocabulary, as Herodotus did for what he called "Scythian".
Document 11: Iranian languages: What is known in Iranian linguistic history as the "Middle Iranian" era is thought to begin around the 4th century BCE lasting through the 9th century. Linguistically the Middle Iranian languages are conventionally classified into two main groups, Western and Eastern.
Document 12: Iranian languages: The multitude of Middle Iranian languages and peoples indicate that great linguistic diversity must have existed among the ancient speakers of Iranian languages. Of that variety of languages/dialects, direct evidence of only two have survived. These are:
Document 13: Iranian languages: Two of the earliest dialectal divisions among Iranian indeed happen to not follow the later division into Western and Eastern blocks. These concern the fate of the Proto-Indo-Iranian first-series palatal consonants, *ć and *dź:
Document 14: Iranian languages: Old Persian is the Old Iranian dialect as it was spoken in south-western Iran by the inhabitants of Parsa, who also gave their name to their region and language. Genuine Old Persian is best attested in one of the three languages of the Behistun inscription, composed circa 520 BC, and which is the last inscription (and only inscription of significant length) in which Old Persian is still grammatically correct. Later inscriptions are comparatively brief, and typically simply copies of words and phrases from earlier ones, often with grammatical errors, which suggests that by the 4th century BC the transition from Old Persian to Middle Persian was already far advanced, but efforts were still being made to retain an "old" quality for official proclamations.
Document 15: Western Iranian languages: The Western Iranian languages are a branch of the Iranian languages, attested from the time of Old Persian (6th century BC) and Median.
