Best performances by men and women open-water swimmers during the ‘English Channel Swim’ from 1900 to 2010
2012
Eichenberger, Evelyn | Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Rosemann, Thomas | Lepers, Romuald; International audience; ''Little research has examined ultra-endurance swimming performances. The 'English Channel Swim', where swimmers have to cover a distance of 32 km between England and France represents a unique long-distance, open-water, sea-swimming challenge, and each year swimmers from all over the world try to succeed in this challenge. The best times in minutes and the nationality of successful men and women swimmers were analysed from 1900 to 2010. A total of 1,533 swimmers (455 women and 1,078 men) from more than 40 countries have successfully completed…
Patients' and therapists' experiences of general change mechanisms during bug-in-the-eye and delayed video-based supervised cognitive-behavioral ther…
2016
Objective This secondary analysis of a randomized controlled trial investigated whether bug-in-the-eye (BITE) supervision (live computer-based supervision during a psychotherapy session) affects the manner in which patients and therapists experience general change mechanisms (GCMs) during cognitive-behavioral therapy (CBT). Method A total of 23 therapists were randomized either to the BITE condition or the control condition (delayed video-based [DVB] supervision). After each session, both patients (BITE: n = 19; DVB: n = 23) and therapists (BITE: n = 11; DVB: n = 12) completed the Helping Alliance Questionnaire (HAQ) and the Bernese Post Session Report (BPSR). The HAQ total score and the 3 …
A reliable CSMA protocol for high performance broadcast communications in a WSN
2014
Wireless Sensor Networks have been identified as a promising technology to efficiently perform distributed monitoring, tracking and control tasks. In order to accomplish them, since fast decisions are generally required, high values of throughput must be obtained. Additionally, a high packet reception rate is important to avoid wasting energy due to unsuccessful transmissions. These communication requirements are more easily satisfied by exploiting the broadcast nature of the wireless medium, which allows several simultaneous receptions through a unique node transmission. We propose a Medium Access Control protocol that ensures, simultaneously, high values of throughput and a high packet re…

Personalized multimedia touristic services for hybrid broadcast/broadband mobile receivers
2010
This paper presents the topology of a multimedia tourism service that targets mobile devices equipped with broadband and either multicast or broadcast access capabilities. Multicast / Broadcast access is used to handle the delivery of multimedia data to many simultaneous users in the service area. The solution adopted is based on existing standards for mobile TV services, but introducing features that enable the provision of generic multimedia services on top of mobile hybrid broadband and broadcast networks. Furthermore, this paper shows how to use standardized interfaces originally defined for interactive mobile TV broadcasting to build personalized mobile multimedia services that do not …
Design of an efficient digital down-converter for a SDR-based DVB-S receiver
2007
This paper presents the design of an area-power efficient digital down-converter suitable for broadband communication systems. The DVB-S standard has been used as a design example. It has been shown that by selecting a bandpass sampling to generate only one spectral image, the case in which the relationship between the digital carrier frequency and the sampling frequency is 1/4, not only gives the smallest area but the lowest power consumption.
Looking over the channel: The balance of media coverage about the “refugee crisis” in Germany and the UK
2022
Abstract This study compares the balance of newspaper and television news coverage about migration in two countries that were differently affected by the so-called “refugee crisis” in 2015 in terms of the geopolitical involvement and numbers of migrants being admitted. Based on a broad consensus among political elites, Germany left its borders open and received about one million migrants mainly from Syria during 2015. In contrast, the conservative British government was heavily attacked by oppositional parties for closing Britain’s borders and, thus, restricting immigration. These different initial situations led to remarkable differences between the news coverage in both countries. In line…
Broadcasting Indigenous Voices
2008
Ethnic minority media embody much of the multiculturalist, multilingual and transnational changes in the media landscape and in the wider societal frame as well. Often minority media aim at providing relevant information, but also alternative publicity and empowering experiences in regard to their own identity, language and culture. Through an analysis of journalists' interviews and ethnographic data, this article examines how these tendencies, possibilities and limitations are played out in the indigenous Sami media. The findings suggest that the Sami journalists have managed to provide an alternative public space and contribute to linguistic revitalization. Yet, working within translocal …
Audiovisual Representation in Spanish and European Election Debates
2020
The presence of ever more conflicting stances between Europhiles and Eurosceptics has revealed some audiovisual discourses unknown until now. The fragmentation of inconclusive narrative discourse and staged situations with a clear intent to clash all make it necessary to analyse in detail the role given by the audiovisual media to the European process of democratisation. This study addresses the audiovisual discourse in Spanish public television (TVE) with the intention of discovering how the different topics addressed in debates are dealt with in audiovisual production, and whether those topics have benefited from certain decisions by the production team that are subjective a priori. Using…
Filecasting for streaming content delivery in IP datacast over DVB-H systems
2008
In this paper we investigate the potential gain that can be obtained in DVB-H by delivering streaming content as a succession of time-constrained flies using Application Layer - Forward Error Correction (AL-FEC) for improving the reception for mobile terminals. Compared to the conventional approach with link layer MPE-FEC, this technique allows to increase the robustness of the DVB-H transmission not only as a function of the capacity devoted for error repair (FEC overhead), but also as a function of the number of data bursts coded jointly ("file" or, source data block, size). The main drawback of this approach is an increase of the network latency proportional to the source block size, tha…
