W prezentowanych zestawieniach zostały uwzględnione programy radiowe, których udział w czasie słuchania na terenie danego województwa wyniósł co najmniej 0,4%. Wyniki zostały porównane z poprzednim kwartałem, przy czym pod uwagę wzięto tylko te zmiany wskaźników słuchalności, które są znaczące statystycznie. Przy każdym województwie została odnotowana wielkość populacji oraz wielkość badanej próby (im mniejsza próba, tym większy błąd statystyczny).

    Adding Support for Jamendo and Magnatune to Rhythmbox on Linux

    Walking in Light with Christ - Faith, Computing, Diary Articles & tips and tricks on GNU/Linux, FreeBSD, Windows, mobile phone articles, religious related texts http://www.pc-freak.net/blog Adding support for Jamendo and Magnatune to Rhythmbox on Linux Author : admin I'm using rhythmbox to play music on my Debian Linux. Rhythmbox is a good substitute for both audacious and xmms. XMMS is already very obsolete and it often crashes because of some of it's plugins. On the other hand audacious is sometimes having problems on my notebook working with it's alsa plugin or pulseaudio especially if I play something in youtube. With audacious my songs sometimes got stucked for some weird reason. With rhythmbox I have never experienced this kind of issues. Considering the fact that I'm a GNOME user rhythmbox is even more attractive for me. During about 2 years ago I've heard about the Jamendo - community of free, legal and unlimited music published under the Creative Commons licenses. Just about 10 months ago I've also discovered magnatune which is also a radio which allows free listening online of it's whole online catalogue. That's why it was really interesting for me to have this two nice music streaming services directly into my rhythmbox. I was very happy to discover that already a plugin that embeds the Jamendo and Magnatune Support to the Rhytmbox program. To enable Rhythmbox to support Magnatune and Jamendo type in your root terminal: debian:~# apt-get install gmpc-plugins gmpc-plugins-dbg debian:~# apt-get rhythmbox-plugins It's very likely that the rhythmbox-plugins might be already installed on your Linux, anyways I put the command above just in case if for some reason it's not installed.

    The Behringer PODCAST & RECORDING

    PODCAST & RECORDING QUICK-START GUIDE Welcome to the Behringer PODCAST & RECORDING quick-start guide Thank you for choosing one of our podcast-capable recording products. This top-notch hardware bundle lets you creatively produce professional-sounding podcasts, voice-over sessions, narration, and music projects for online distribution. If you’re a vlogger, you’ll have a superb pack of equipment to dramatically enhance the audio quality of your videos compared to the built-in camera microphone, giving your broadcasts a more professional appeal. Move up to the next step in the evolution of broadcasting and free yourself from the limitations of conventional communication. Podcasting Basics Before you get started, it is important to understand some of the terminology and uses surrounding the emerging field of podcasting. Podcasting is a term derived from the combination of the words “iPod” and “broadcasting,” and is defined as the distribution of audio or video files, such as radio programs or music clips, over the Internet. This is accomplished by using one of two syndication techniques that allow users to access media on such portable media devices as smart phones, tablets, MP3 players, and laptop computers. RSS (Really Simple Syndication) and Atom are Web content syndication formats written in XML that provide either podcast content or summaries that link to content and additional file information. Podcast is a feed of audio or video files placed on the Internet for public access. Anyone can subscribe to the feed and download the media files. This allows you to collect programs from a wide range of sources for listening or viewing media content, either online or offline with your computer or an appropriate portable device.

    Agency and Exchange: an Ethnography of a Heroin Marketplace

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by espace@Curtin Faculty of Health Sciences National Drug Research Institute Agency and exchange: an ethnography of a heroin marketplace Robyn Dwyer This thesis is presented for the Degree of Doctor of Philosophy of Curtin University of Technology May 2009 Declaration To the best of my knowledge and belief this thesis contains no material previously published by any other person except where due acknowledgement has been made. This thesis contains no material which has been accepted for the award of any other degree or diploma in any university. Signature: …………………………………………. Date: ………………………... Abstract This thesis is concerned with the exchange of heroin in localised, street-based marketplaces. Commercial exchange of heroin in such sites has been a characteristic of the Australian heroin scene since the early 1990s. Although some qualitative investigations have been undertaken, the dominant approach to understanding these sites in Australia has been quantitative (primarily epidemiological and criminological). These efforts largely adopt a narrow and under-developed conception of ‘markets’ and much of this work adopts a narrow and circumscribed conception of the subjects who act within these sites. In contrast, this thesis is positioned within a long tradition of ethnographic accounts of drug users as active agents and of drug markets as embedded in particular social, cultural and economic contexts. In this thesis, I explore two related questions: 1) what are the social relations and processes constituting street-based drug markets, and 2) how do participants in these street-based drug markets express agency, given that, in public and research discourses, they are often understood and depicted either as lacking agency or as expressing agency only through profit-seeking, criminality or both.
