1. 1. The sounds of radio : on radio as an auditive means of communication

   Författare :Carin Åberg; Uwe Hasebrink; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; radio; communication theory; sound-meaning; radio listening; radio programmes; programme analysis.; medie- och kommunikationsvetenskap; Media and Communication Studies;

   Sammanfattning : The primary purpose of this doctoral thesis is to present a theoretical framework for analysis of communication through radio, taking the sounding dimension of the medium as a primary characteristic. My theoretical approach is manifold, but I explicitly use writings from the field of ethnomethodology/microsociology (linguistic communication) of Alfred Schutz (sociology of everyday life) and Gerhard Maletzke (mediated communication).

3. 2. Lokalradio och kommersiell radio 1975−2010 : En mediehistorisk studie av produktion och konkurrens

   Författare :Michael Forsman; Madeleine Kleberg; Per Jauert; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; radio history; competition; intermedial; intramedial; media production; media politics; local radio; commercial radio; branding; formatting; scheduling; Media and communication studies; Medie- och kommunikationsvetenskap; medie- och kommunikationsvetenskap; Communication Studies; Other research area;

   Sammanfattning : The main question in this dissertation is: How can the emergence of local and commercial radio and the ensuing changes within each be understood in relation to intermedial and intramedial competition? This overarching question is broken down into four research questions. What driving forces contributed to the implementation of local and commercial radio respectively? (How can the competitive context of these two radio forms be described and periodized? In what ways have the practices of producing radio output, radio audiences and brands changed during the period covered by this study? What similarities and differences have emerged between local radio and commercial radio over time? This study can be seen as an institutional media history, focusing on two distinctive periods in the history of Swedish radio and television, Decentralization (1977-1987) and Commercialization (1987 onwards).

4. 3. Lokal radio och TV : en analys av publikstruktur och deltagande

   Författare :Anders Lindblad; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; RADIO; LOCAL TELEVISION; AUDIENCE; PARTICIPATION; DEMOCRACY; PUBLIC ACCESS; NEIGHBOURHOOD RADIO; SWEDEN; CABLE TELEVISION;

   Sammanfattning : The background to the thesis is the decentralization trend which has led to the development of various forms of local radio and television in a number of countries, including Sweden. Common to all official statements regarding the emergence of local media is the theme that local media has a potential for strengthening democracy. LÄS MER

5. 4. Impulse Radio UWB for the Internet-of-Things : A Study on UHF/UWB Hybrid Solution

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-Wideband; impulse radio; IR-UWB; RFID; asymmetric links; UHF UWB hybrid; wireless sensing; energy detection; low power; radio receiver; positioning; Internet-of-Things;

   Sammanfattning : This dissertation investigates Ultra-Wideband (UWB) techniques for the next generation Radio Frequency Identification (RFID) towards the Internet-of-Things (IoT). In particular, an ultra-high frequency (UHF) wireless-powered UWB radio (UHF/UWB hybrid) with asymmetric links is explored from system architecture to circuit implementation. LÄS MER
