Texto completoResumen
The aim of this thesis is to research in the use of emerging TV white space communications, implementing a geo-location database system. For that, some research and theoretical studies related to cognitive radio and TV white space communications will be done first, focusing on current activities, standarization processes, commercial approaches and related projects. Once the background and the present TV white space communications status is analyzed, a geolocation database system will be designed and developed to prove the potential of this technology. The operation of the database system will be demonstrated through a web interface. In this way, an open and publicly accessible geo-location database system implementation and structure will be created (note that even if several database system creation initiatives are taking place, most of them are private). However, due to the lack of official regulatories, established standards, and actual transmission data (data from TV broadcasters, wireless microphones etc.), only an initial TV white space database system demo will be implemented to model the operation of the same. It will be possible to access and query this database systemthrough a simple web interface for the Oslo area. After analyzing the results of the implementation and looking to other TV white space initiatives, some considerations for future work will be concluded.

Texto completoResumen
Spectrum scarcity is an important challenge faced by high-speed wireless communications. Meanwhile, caused by current spectrum assignment policy, a large portion of spectrum is underutilized. Motivated by this, cognitive radio (CR) has emerged as one of the most promising candidate solutions to improve spectrum utilization, by allowing secondary users (SUs) to opportunistically access the temporarily unused spectrum, without introducing harmful interference to primary users. Moreover, opening of TV white space (TVWS) gives us the con dence to enable CR for TVWS spectrum. A crucial requirement in CR networks (CRNs) is wideband spectrum sensing, in which SUs should detect spectral opportunities across a wide frequency range. However, wideband spectrum sensing could lead to una ordably high sampling rates at energy-constrained SUs. Compressive sensing (CS) was developed to overcome this issue, which enables sub-Nyquist sampling by exploiting sparse property. As the spectrum utilization is low, spectral signals exhibit a natural sparsity in frequency domain, which motivates the promising application of CS in wideband CRNs. This thesis proposes several e ective algorithms for invoking CS in wideband CRNs. Speci cally, a robust compressive spectrum sensing algorithm is proposed for reducing computational complexity of signal recovery. Additionally, a low-complexity algorithm is designed, in which original signals are recovered with fewer measurements, as geolocation database is invoked to provide prior information. Moreover, security enhancement issue of CRNs is addressed by proposing a malicious user detection algorithm, in which data corrupted by malicious users are removed during the process of matrix completion (MC). One key spotlight feature of this thesis is that both real-world signals and simulated signals over TVWS are invoked for evaluating network performance. Besides invoking CS and MC to reduce energy consumption, each SU is supposed to harvest energy from radio frequency. The proposed algorithm is capable of o ering higher throughput by performing signal recovery at a remote fusion center.

Esta tese tem como objetivo a caracterização experimental do canal de propagação na faixa de UHF para as aplicações em sistemas de TV Digital. Através de campanhas de medições de campo em condições que aproximam a operação real destes sistemas foi levantado um conjunto de dados que permitiu: a avaliação de métodos de previsão da perda média de propagação em regiões urbanas densas; a determinação do retardo médio e banda de coerência do canal nestas regiões, em condições de recepção externa e interna; a caracterização estatística do espalhamento de retardos do canal; e a simulação do canal em diferentes condições de recepção para obtenção de seu perfil de retardos. São apresentadas as três campanhas de medidas realizadas, incluindo a descrição das regiões e configurações de medição, técnicas de medição e processamento de dados utilizados. A seguir é apresentada uma análise da perda média de propagação nas medições realizadas e a comparação com as previsões fornecidas para os mesmos percursos pela implementação do modelo do ITU-R. A caracterização em banda larga do canal é realizada pela modelagem estatística do perfil de retardos de multipercurso do canal. Finalmente, são apresentados os resultados de simulações para obtenção do perfil de retardos do canal com base nos resultados experimentais obtidos e a modelagem estatística desenvolvida nesta tese.

Texto completoResumen
This research presents the design of a two-element radio interferometer capable of performing complex correlation. With the development of sophisticated radio astronomy instruments, particularly in South Africa, there is a need to develop an affordable educational instrument which can be used to demonstrate the fundamental concepts of radio interferometry to university students. The mass production of satellite TV equipment has resulted in relatively sensitive radio frequency (RF) equipment such as parabolic reflector dishes and low-noise block down-converters (LNBs) being available at significantly reduced costs. This served as the front-end of the interferometer which was used to observe the sun between 10.70 GHz - 12.75 GHz (RF). The LNB then down-converted these to an intermediate frequency (IF) between 0.95 GHz - 2.15 GHz. The LNBs were modified to make use of a common 25 MHz reference, which ensured that the observed fringes were only as a result of the source's geometric time delay. A power detector was also designed since the adding interferometer architecture was chosen. This power detector included the Analog Devices LT 5534 power detector integrated circuit (IC) and a Teensy 3.6 microcontroller. The calibrated power detector could detect signals as weak as - 60 dBm and showed less than 21 mV error in output for input signals in the range [- 50 dBm, -30 dBm]. The modified LNBs experienced issues, in particular the presence of a spurious LO signal, which distorted initial observations of the sun. This was resolved by the design and manufacture of narrowband hairpin filters and quarterwavelength stub filters which were used to isolate the IF band between 1.05 GHz - 1.15 GHz (corresponding RF between 10.80 GHz - 10.90 GHz). This also improved the interferometer's resolution. A series of filter-integrated Wilkinson power dividers and branchline couplers were designed to filter and further separate signals into in-phase and quadrature-phase (I-Q) components - these were required for complex correlation. The integrated quarter-wavelength stub filter and Wilkinson power divider achieved a maximum amplitude imbalance of 0.13 dB and phase imbalance of 0.9◦ between output ports. The integrated quarter-wavelength stub filter and branchline coupler achieved a maximum amplitude imbalance of 0.13 dB and phase imbalance of 91.1◦ between output ports. These results closely agreed with the simulated performance. First light was observed on the 5th December 2020 when the sun was successfully detected using the coherent two-element interferometer along a 1.1 m baseline. Other tests included using the observed fringe phase to verify the physical baseline. A theoretical baseline of 1.11 m was calculated for a physical baseline of 1.3 m indicating an error of less than 0.2 m. The sun's fringe frequency and amplitude was also observed for varying baselines - the sun was resolved along a 3 m baseline. Finally, full-system observations of the sun were conducted. These included observing the sun's cosine and sine fringes, which indicated that the analogue complex correlator was operating correctly. Thus, the primary goal of this project had been fulfilled. Specifically, developing a low-cost, educational two-element radio interferometer capable of detecting the sun.

Texto completoResumen
Att vi ser minst en sportreferent vid varje match eller i andra idrottssammanhang är idag en självklarhet. Det finns kända och mindre kända referenter. Men hur har de mest etablerade referenterna tagit sin plats och blivit dem som vi så kallat känner till? För vissa räcker det att höra rösten och man vet direkt vem det är, andra har börjat synas mer och mer under sändningarna. Till en början handlade det mest om att rösten var talande. För det var ju faktiskt i radio som allting började. Men när TV började sända sport så började den också ta över radiosportens lilla era. Det här är en studie hur sportreferenter etablerat sig ända sedan AB radiotjänst för första gången 1925 började ge ut sändningar som innehöll idrottsarrangemang till dagens TV-sportreferenter. Läsaren kommer att få en inblick hur det är att jobba som referent samt vilka krav som ställs. Men framförallt finns det en historisk berättelse hur TV-sporten tagit över radiosporten allt mer och mer. De slutsatser vi kunde dra var att det finns nästan ingen som är anställd utan utbildning när det kommer till att arbeta som sportjournalist i radio eller TV. Då bland annat både SVT och Sveriges Radio har som krav att även praktikanter måste vara under en journalistisk utbildning. Du kan inte längre säga vad du tycker och vill som sportjournalist, framförallt inte i TV. I radio är det inte lika noga. De första sändningarna handlade mer om att tala om för tittaren hur allting såg ut, idag är det annorlunda och man skapar känslor för publiken för att hålla dem underhållna.

Texto completoResumen
This thesis focuses on learner support in Chinese distance education. It draws a picture of Chinese modern distance education, covering the major issues in the field of learner support, and small group work as peer support. The aim of the study is to find out whether or not the learner support, that distance students at university level obtained, has the tendency to support students’ deep learning. The aim has been achieved by examining learner support in six institutions of ICT-based distance education in China. Three other sources of learner support are investigated. The main objectives of the study are: 1) to describe the distance students’ characteristics; 2) to examine their learning habits, learning organizations, and their interactions; 3) to investigate the student support provided by the institutions; family support; societal support; and peer support in the form of small group work. The purpose of this study is to define current practices of learner support in the six distance education institutions, determining the extent of similarities and differences on learner support services among these institutions. The study is applying a case-study approach, using qualitative and quantitative methods to investigate the six Chinese distance education institutions. During the first stage, several field visits were conducted in different research sites with on-site participant observation, non-participant observation and interviews for obtaining knowledge of Chinese distance education. In the second stage, a survey with a student questionnaire was distributed to students present and others online, in total 587. In addition, semi-structured interviews with staff members (administrators, instructors and tutors), individual students, and student focus groups were performed. The present research is one of the few in-depth case studies that focus on the relation between learner support system and different approaches to learning. On the basis of these research findings, the importance of a well-designed learner support system for the distance learner, a system for fostering creative, critical or independent thinking skills, or deep learning, in line with Chinese cultural and social conditions, is underlined.

Texto completoResumen
Esta tese traz reflexões sobre a construção do campo público da televisão brasileira tomando por base os sistemas adotados em países como Inglaterra, Japão, Estados Unidos, Canadá, Colômbia, Venezuela e Brasil; localizando em cada experiência informações sobre a estrutura, os modelos de gestão e de financiamento, os instrumentos de participação popular e o perfil da programação. Especificamente no Brasil, apresentamos o percurso histórico das TVs públicas, pontuando dois momentos fundamentais: o primeiro, em 1995, quando as operadoras de TV a Cabo, em cumprimento da Lei da Cabodifusão, passaram a disponibilizar os canais básicos de utilização gratuita, garantindo a oferta de sinal para as TVs legislativas, comunitárias e universitárias e do Poder Judiciário, a partir de 2002. Estas, juntamente com as emissoras educativo-culturais que já exibem em sinal aberto, passaram a integrar o que se convencionou chamar de campo público da televisão. O segundo momento, em 2006, é marcado pelo Decreto que dispõe sobre a implantação do Sistema Brasileiro de TV Digital Terrestre. O documento prevê a destinação de canais para a exploração direta da União Federal e uma faixa entre os canais 60 e 69 para as emissoras públicas espaço esse ainda cobrado pelo segmento, que exibe majoritariamente no cabo. Nesse contexto, são apresentadas as especificidades da TV universitária enquanto mídia especializada do ensino superior, com foco nos objetivos de comunicação o ensino, a pesquisa e a extensão. Essas informações servem de base para cumprir nosso objetivo: compreender como o segmento vem construindo sua identidade, a partir do levantamento do perfil dessas TVs quanto à sua institucionalização, formas de gestão e financiamento, participação acadêmica na produção de conteúdo, programação e alternativas de veiculação. Para isso, realizamos uma pesquisa de campo e, em um universo de 1.662 instituições de ensino superior das cinco regiões brasileiras, localizamos 151 TVs. Embora, à primeira vista, essa presença pareça tímida, os resultados revelam um crescimento de 755%, tomando como referência o ano de 1995, quando as experiências de produção televisiva em ambiente universitário não passavam de 20 em todo o país. Os resultados desse levantamento apontam para uma realidade sobre a qual o segmento universitário ainda não vem dando a devida atenção: cresce o número de TVs operando no cabo, é intensa a luta por um espaço no espectro da TV digital aberta, mas as poucas experiências na web se limitam a postar os programas nos portais das instituições ou das próprias TVs. Ou seja, a web está relegada a um suporte secundário para a distribuição de conteúdo, na contramão da crescente migração dos telespectadores para a rede mundial de computadores. Assim, apresentamos uma proposta de WebTV universitária que vá além do processo de produção, mensagem e recepção, privilegiando o fluxo dialógico proporcionado por canais reais de interatividade, no qual o receptor pode também ser um produtor de informação.This dissertation ponders about the construction of the Brazilian public TV field taking into account the systems adopted by countries such as Japan, the United States, Canada, Colombia, Venezuela, and Brazil; picking up in each experience information on the structure, management and financing models, the means of popular participation, and programming profile. As far as Brazil is concerned, we present the historical development of public TV by bringing into relief two fundamental moments: the first one, in 1995, when cable TV operators, in order to observe the Law of Cable TV Broadcasting, began to make free basic channels available, by supplying TV broadcasting to the Legislative and Judiciary Powers, communities, universities, from 2002 on. Those TV operators, along with the educational and cultural ones which are already broadcasting open TV signals, became what is being conventionally called the television public field. The second one, in 2006, is outstanding due to the Decree which deals with the implementation of the Brazilian Terrestrial Digital TV System. The decree at issue reserves channels for direct exploitation by the Union and about 60 and 69 channels meant for public TV systems, a number demanded by that sector, which are mostly broadcast by cable. Within such a context, we point out the peculiarities of the university TV system as a specialized medium for higher education, focusing on the aims of communication learning, research, and provision of community services. Such a piece of information serves as a basis for achieving our aim: to understand how that sector is developing its identity by constructing the profile of those TV systems concerning their organization, management and financing strategies, academic participation in order to provide content development, program schedules and broadcast alternatives. With that purpose in mind, we carried out a field research and, among 1,662 higher education institutions spread over the five Brazilian geographical areas, we managed to find out 151 TV stations. Although, at first glance, such a figure seems to be rather small, the outcomes achieve a 755% growth, from 1995 on, when experiences in making TV programs within the university environment were confined to only 20 throughout Brazil. The outcomes of that survey show a reality which has not been duly taken into consideration by universities: the number of cable TV stations increases, the fight for space in the open digital TV system is fierce, but scarce experiences in the Web are confined to setting up programs in the web sites of such institutions or of the very TV stations. In other words, the Web is confined to a subordinate supporting role in the distribution of content broadcasting, contradicting the increasing TV viewers migration to the world computer network. Therefore, we proposed a university web TV which goes beyond the processes of production, message, and reception, by furthering the dialogical flow provided by real interactive channels, in which the receptor may also become an information provider.

O objetivo desta dissertação é compreender como a ciência é utilizada nas narrativas dos anúncios publicitários televisivos veiculados, no período de junho a novembro de 2013, nas emissoras TV Liberal e Record Belém, ambas localizadas em Belém do Pará. Nossa proposta é delineada como um desdobramento da pesquisa Representações da Mulher Cientista na TV Brasileira e no Imaginário de Adolescentes, na qual percebemos a recorrência da utilização da ciência em anúncios publicitários na grade de programação da TV aberta. Com base no que foi coletado naquela pesquisa, configura-se um novo corpus composto por 83 anúncios publicitários, com objetivo de analisar como a ciência configura as narrativas publicitárias. A partir de pesquisa e revisão bibliográfica discutimos a publicidade como narrativa fortemente articulada ao mercado e ao nosso cotidiano, revelando-se uma mediação de processos comunicacionais e construtora de modelos (TOALDO, 2005; GOMES, 2008; PIEDRAS, 2009; TRINDADE, 2012; MOTTA, 2013). Para analisar o uso da ciência nessas narrativas e discutir a relação que esse uso estabelece com a sociedade, seguimos a proposta analítica de Motta (2013), composta por sete movimentos. Esses movimentos analíticos nos permitem decompor e recompor as narrativas com foco nos processos de comunicação que perpassam os anúncios publicitários televisivos. Identificamos e discutimos nove estratégias de utilização da ciência na construção das narrativas publicitárias, que são: (i) o componente científico; (ii) o ambiente científico; (iii) o convite à experimentação; (iv) a relação com a inovação; (v) a ficção e a realidade; (vi) as animações e ilustrações científicas; (vii) os cientistas e especialistas como personagens; (viii) as celebridades como personagens; (ix) os não especialistas como personagens. Tais estratégias estabelecem uma noção de que o conhecimento científico é fonte de soluções para problemas cotidianos ao propiciar um ambiente de criação e inovação capaz de gerar tecnologias que promovem novas práticas sociais e se incorporam ao dia a dia dos sujeitos sociais.
The objective of this dissertation is to understand how science is used in the narratives of advertisements broadcasted, between June and September of 2013, on TV Liberal and Record Belém broadcasters, both located in Belém, Pará. Our proposal is an outcome of the research “Representations of Women Scientist at Brazilian TV and on Teenagers Imaginary”, in which we perceived the occurrence of the utilization of science on advertisements in the program schedule of free-to-air TV. Using the data collected in that research, we made a new corpus of 83 advertisements aiming to analyze how science configure the advertising narratives. With the research and bibliographic review, we saw that advertising is heavily articulated to the market and our day-to-day lives, revealing itself as a mediation of communicational processes and a model constructor (TOALDO, 2005; GOMES, 2008; PIEDRAS, 2009; TRINDADE, 2012; MOTTA, 2013). To analyze the use of science in these narratives and discuss the relation that this use stablishes on society, we follow the analytic proposal of Motta (2013) that consists on seven acts. These analytic acts allow us to decompose and recompose the narratives focusing on the processes of communication that pass through television advertisements. We identified and discussed nine strategies of science utilization on the construction of advertising narratives, which are: (i) the scientific component; (ii) the scientific environment; (iii) the invitation to experimentation; (iv) the relation with innovation; (v) fiction and reality; (vi) the scientific animations and illustrations; (vii) the specialist and scientist characters; (viii) the celebrity characters; (ix) and the non-specialist characters. Those strategies stablish a notion that the scientific knowledge is a source of solutions to everyday problems by providing a creation and innovation environment capable of generating technologies that promote new social practices and are incorporated to the daily lives of the social subjects.

Texto completoResumen
SVT arbetar inom public service-sfären och försöker efterfölja ett sändningstillstånd där objektivitet förespråkas. Under en längre period hade SVT monopol på TV-sändningar, men 1987 hävdes monopolet och konkurrerande nyhetsmedier gjorde entré på marknaden. Tidigare forskning visar att uppkomsten av konkurrerande nyhetsmedier på marknaden har förändrat sättet att producera nyhetsinslag. Nyhetsmediernas nyhetsinslag har gått mot en mer kommersiell utformning där syftet är att locka till sig tittare. SVT har följt denna trend trots att deras sändningstillstånd förespråkar neutralitet gentemot andra maktsfärer i samhället. Vad som inte framgått av tidigare forskning är om och hur bildsättningen i nyhetsinslagen förhåller sig till objektivitet kontra kommersialism efter avskaffandet av TV-monopolet. Då SVT behållit sitt sändningstillstånd kan det antas att de fortfarande anser sig vara objektiva i sitt bildberättande, men frågan är då om deras syn på objektivt bildberättande har förändrats? För att svara på detta genomfördes en kvalitativ bildanalys av åtta nyhetsinslag med temat katastrofrapportering. Fyra inslag som rapporterar om Tjernobylkatastrofen 1986 ställs mot fyra inslag om flodvågskatastrofen i Asien 2004. Den första katastrofen ägde rum före TVmonopolets avskaffande, och den andra efter. Bildberättandet i rapporteringen av katastroferna jämfördes sedan, för att fastslå om den senare katastrofen gestaltats mer kommersiellt än den tidigare. Uppsatsen diskuterar om och hur synen på objektivitet har förändrats hos SVT, och att objektivitet kan komma att fortsätta förändras mot ett mer kommersiellt håll. Studiens slutsats visar att bildberättandet i nyhetsinslagen över Tjernobylolyckan förhöll sig mer till objektivitet, medan nyhetsinslagen över flodvågskatastrofen i Asien lutade mot ett mer kommersiellt bildberättande. Mellan 1980-talets senare hälft och 2000-talets början hade klippbildernas roll förändrats. Den visuella information som tillsammans med reporterrösten till en början utgjorde vad som kan liknas vid bildsatt radio, hade under den senare perioden övergått i en katastroffilm, som underhöll publiken på ett sätt som liknar de kommersiella nyhetsinslagens utformning.

nÃo hÃIn this work I analyze the extent of public journalism in a state television based on case study of television news magazine TV Cearà a state broadcaster considered to be maintained and controlled by the State of Cearà To this end we held initially literature on the category of public sphere and private sphere from studies on the public sphere of Habermas with the support of Arendt Dagnino and Thompson which extend the considerations on the issue confronting with Habermas With that yet worked with the categories of public state television TV Educational TV and private TV and TV commercial based on studies Leal Filho RincÃn MartÃn-Barbero and other authors who support the idea that public television is different from other TV by have control of the company on its programming and administration with no links to political and economic powers seek Niskier on the grounds of the significant presence of state television in Brazil because it is linked historically to the government policy of education with the creation of dozens of TV character And in educational studies Mattos arguments seek to establish a solid structure of commercial TV in Brazil for their close ties with the economic and political power responsible for the consolidation of its influence on society as a daily record of high ratings
Com o presente trabalho, pretendo analisar a dimensÃo pÃblica no jornalismo de uma TV estatal, com base no estudo de caso do telejornal Revista, da TV CearÃ, uma emissora considerada estatal, por ser mantida e controlada pelo Governo do Estado do CearÃ. Para isso, realizamos, inicialmente, pesquisa bibliogrÃfica sobre a categoria de esfera pÃblica e esfera privada, a partir de estudos sobre esfera pÃblica de Habermas, com o apoio de Arendt, Dagnino e Thompson, que ampliam as consideraÃÃes sobre essa temÃtica confrontando-se com Habermas Com isso trabalhamos ainda com as categorias de TV pÃblica TV estatal TV Educativa e TV privada ou TV comercial com base nos estudos de Leal Filho RincÃn MartÃn-Barbero entre outros autores que reforÃam a idÃia de que a TV pÃblica se diferencia das outras TVs por ter o controle da sociedade sobre a sua programaÃÃo e administraÃÃo sem ligaÃÃes com os poderes polÃticos e econÃmicos Buscamos em Niskier os fundamentos da presenÃa significativa da TV estatal no Brasil por estar ligada historicamente Ãs polÃticas governamentais de educaÃÃo com a criaÃÃo de dezenas de TVs de carÃter educativo E nos estudos de Mattos buscamos os argumentos para comprovar a estrutura sÃlida da TV comercial no Brasil por seus estreitos laÃos com o poder econÃmico e polÃtico responsÃveis pela consolidaÃÃo da sua influÃncia sobre a sociedade conforme o registro diÃrio dos elevados Ãndices de audiÃncia

Thesis, Jönköping University, HLK. Media and communication science, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-7685.
Texto completoResumen
Uppsatsen syftar till att belysa rekryteringsprocessen och kanalernas, Sveriges Radio, Sveriges Tele-vision, Mix Megapol och TV4, kriterier samt att få en bild över programledarens yrkesroll, utmärkande drag och erfarenhet av rekryteringen. Problemformuleringen består utav hur programledare väljs, utefter vilka kriterier, hur programledaren upplever sin yrkesroll och erfarenheter av rekrytering, samt vad som utmärker en programledare för underhållningsprogram inom radio och TV, public service och kommersiella medier. Vi har undersökt hur rekryteringsprocessen av programledare inom underhållning för rikstäckande radio och TV går till, och jämfört processen mellan public service och kommersiella medier. Detta såg vi som intressant, då det är en outforskad yrkesroll, som har en unik rekryteringsprocess och vi ansåg det vara tänkvärt att göra en jämförelse mellan kanalerna, public service och kommersiella medier. Under-sökningen består utav kvalitativa intervjuer med elva utvalda rekryterare och programledare i branschen. Uppsatsen bygger på tre teoretiska modeller; rekryteringsvägar enligt Lars-Åke Engblom, rekryteringsprocessen med bedömning av Lars Prien och även hans teori kring urvalet. Till uppsatsen kan vi också koppla Bourdieus teori kring det kulturella kapitalet. I slutdiskussionen har vi sammanfattat nuvarande rekrytering i punktform. Resultatet kan sammanfattas i en uppdaterad modell av rekryteringssätt, som vi presenterar. Sammanfattningsvis visar undersökningen skillnaderna mellan public service och kommersiella kanaler, både vad det gäller process och kriterier vid anställning av programledare, samt programledares syn på detta.

Texto completoResumen
Denna uppsats undersöker könsmarkering i introduktionen av sportnyheter. Syftet med uppsatsen är att undersöka om och i vilken utsträckning könsmarkering med dam och herr används i introduktionen av sportnyheter, alltså om nyheten är tydlig med om det handlar om dam- respektive herrsport. Fokus kommer ligga på om, och i så fall hur, könsmarkering för kvinnor och män används i språket. Uppsatsen kommer även undersöka om det finns någon skillnad ur ett historiskt perspektiv samt om nyheten presenteras på TV eller på radio. Metoden för analys av det insamlade materialet har varit genom observation av sportnyheter på TV och radio där det har antecknats vad nyheten handlade om och dam eller herr eller ingen könsmarkering användes. Resultatet visar att den procentuella andel könsmarkering i damsportnyheter har varit väsentligt mycket högre än könsmarkering i herrsportnyheter historiskt men att det har minskat över tid. Idag sker könsmarkering främst i radio om damsportnyheter.

The results of the fourth part of the Rhodes University Skymap Program are presented. The observations cover the area of sky between right ascension 14h00m and 02h30m and declination -26⁰ and + 13⁰ at a frequency of 2.3 GHz. Contour maps of this region, with a resolution of 0.38⁰, are presented. Various methods of reducing the effect of the Galactic disc emission are analyzed. The results demonstrate the effectiveness of one of these methods in the production of a flat base level. The filamentary structure of the North Polar Spur is enhanced and results are obtained which support current theories of the origin of this object. The HII region surrounding Ophiuchi is examined in detail. A number of parameters are derived for the HII region. The spur associated with the HII region S54 is also examined. A listing of 1105 point sources appearing in the maps is presented. The limiting flux density of this listing is 0.5 Jy

The relations between the camps university / scientific and the television and the tensions that arose for the establishment of a television field are the subject of this university. The main objective of this work is based on the analysis of the university campus and field television - understand - the role played by TV at university overlap with those fields. Was taken as a paradigmatic example of the televisions that are part of the University Channel University of São Paulo (SP-CNU), the first university channel in the country to make use of theCable Law (8977) which in its Article 23 provides for free use of universities its area of service a television channel. The theoretical approach was in Bourdieu and the concepts of habitus and field his main references. The methodology included literature searches and field with four (4) agents(directors) of TV universities that participate in the CNU-SP
As relações entre os campos universitário/científico e o televisivo e as tensões que se criaram para a constituição de um campo televisivo universitário são objeto deste trabalho. O objetivo principal do trabalho é a partir da análise do campo universitário e do campo televisivo compreender o lugar ocupado pela tevê universitária na imbricação com esses campos. Tomou-se como exemplo paradigmático as televisões universitárias que fazem parte do Canal Universitário de São Paulo (CNU-SP), primeiro canal universitário do País a fazer uso da Lei do Cabo (8.977) que em seu artigo 23 disponibiliza para uso gratuito das universidades de sua área de prestação de serviço um canal de televisão. A fundamentação teórica teve em Bourdieu e nos conceitos de habitus e campo suas principais referências. A metodologia incluiu pesquisas bibliográficas e de campo com 4 (quatro) agentes (diretores) das tevês universitárias que participam do CNU-SP

A pesquisa aproveitou a proximidade entre as atividades laboratoriais do Curso de Comunicação Social do Centro Universitário de Votuporanga com a TV universitária da Instituição de Ensino Superior (IES) - denominadas TV Unifev - para propor novos programas. E entre os produtos formatados, elegeu-se , com estudo de caso, o Debate Livre, com duração média de 40 minutos, que abre espaço para a apresentação das atividades de educação e extensão das graduações e suas áreas de conhecimento, oportunizando a conexão da universidade com a sociedade. Produzido com a assinatura Lab.In.TV., o Debate Livre foi inserido na grade de programação da TV Unifev, no canal aberto UHF, em setembro/2010. Uma equipe formada por professores, graduandos e técnicos do Curso de Comunicação - das habilitações de Jornalismo e Publicidade e Propaganda - produziu e gravou semanalmente com a comunidade acadêmica e convidados 14 programas no Laboratório Integrado de Comunicação Social. Ainda em fase de implantação no Brasil, a Televisão Digital (TVD) já experimenta benefícios como melhoria na imagem e som e alguns recursos de interatividade que estão sendo testados. Para viabilizar esta interface, foi desenvolvido um protótipo funcional do episódio sobre o tema Consciência Negra para simular a interatividade do público receptor do Debate Livre.

And among the formatted products, it was chosen, as a case study, the Debate Livre, that lasts 40 minutes, and given opportunity for the presentation of education activities and extension of the graduations and their areas of expertise, allowing the approximation of the university with society. Produced with the signing Lab.In.TV., Debate Livre was inserted in the schedule of TV Unifev, on UHF open channel 55, in september 2010. A group of professors, graduate students and technicians from the Communication Course - qualifications of Journalism and Advertising - weekly produced and recorded with the academic community and guest 14 programs in the Integrated Laboratory of the Social Communication. Still being implemented in Brazil, the Digital Television (DTV) has been experiencing benefits such as improved vision and sound and some interactivity items that are being tested. To facilitate this interface, a working prototype was modeled in the episode about the subject Black Consciousness to simulate the interactivity from the receptor audience of Debate Livre.

A presente pesquisa analisa as representações sobre a região amazônica expressas em dois telejornais exibidos no horário nobre da televisão brasileira. A partir da perspectiva das representações sociais e das teorias do telejornalismo, foram analisados quatro parâmetros: os conceitos de Amazônia adotados nas notícias e reportagens; as representações dos estados da Amazônia Legal e sua relação com a região; os temas segundo os quais a Amazônia aparece em rede nacional; e as diferenciações nas matérias jornalísticas conforme a ausência e presença dos Núcleos de rede locais no processo de produção dos conteúdos. Para tal foram observados os telejornais exibidos entre 14 de junho e 09 de outubro de 2010, totalizando 101 textos jornalísticos. As representações sobre a região parecem estar, neste período, intimamente relacionadas as discursões de desenvolvimento sustentável.
This research analyzes the representations on the Amazon region expressed in two primetime television news shows Brazilian television. From the perspective of social representations and theories of news broadcasting, have been examined four parameters: the concepts of Amazon adopted in the news and reports; the representations of States of the Legal Amazon and its relationship with the region; the themes under which Amazon appears on national television; and the differentiations in stories as the absence and presence of local television in the content production process. For such were observed the news showed between 14 June and 09 October 2010, totaling 101 journalistic texts. Representations about the region seem to be, in this period, closely related to the discourses on Sustainable Development.

Several studies have shown that sociability television network allows the audience to collaborate with content produced collectively. In this context, this paper discussed how the interactive process between Digital TV and social networks - known as Social TV - and this relationship can be an alternative to the public university TVs produce content more quality offering viewers new possibilities for participation. Through an exploratory research and visits to the Digital Video Applications Laboratory (LAVID) UFPB be established that the integration between Public Digital Interactive TV and social networking is possible to happen if we consider that the concept and implementation of the Social TV Digital TV is the result of the integration with social networks. For better understanding of this process, a theoretical proposal was elaborated an interactive program for UFPB TV was demonstrated the importance of Social TV and the university TVs can be a way to stimulate the participation of society in the production of content for Interactive Digital TV Public.
Vários estudos têm mostrado que a sociabilidade da televisão na rede permite que as audiências colaborem com os conteúdos produzidos de forma coletiva. Nesse contexto, o presente trabalho discuti como o processo interativo entre a Televisão Digital e as redes sociais – conhecido como TV Social – e se essa relação pode ser uma alternativa para as TVs públicas universitárias produzirem conteúdo com mais qualidade oferecendo ao telespectador novas possibilidades de participação. Através de uma pesquisa exploratória e de visitas feitas ao Laboratório de Aplicações de Vídeo Digital (LAVID) na UFPB foi possível estabelecer que a integração entre TV Pública Digital Interativa e as redes sociais é possível de acontecer se considerarmos que o conceito e aplicação da TV Social é resultado da integração da TV Digital com as redes sociais. Para melhor entendimento desse processo, elaborou-se uma proposta teórica de um programa interativo para a TV UFPB em que se pôde comprovar a importância da TV Social bem como que as TVs universitárias podem ser um caminho para estimular a participação da sociedade na produção de conteúdo para a TV Pública Digital Interativa.

Texto completoResumen
Este trabalho apresenta uma análise da propagação de sinais de TV Digital na faixa de UHF em ambientes internos. A partir da comparação de alguns modelos de propagação interna e externa referenciados na literatura para outras faixas de frequência e aplicação, um algoritmo foi desenvolvido com a finalidade de gerar um mapa de cobertura de sinal que exibe a potência de recepção no ambiente interno. Estas simulações foram comparadas com medidas em campo a partir de dois estudos de caso. O primeiro avalia a cobertura de sinal em um andar inteiro de um prédio e o segundo no interior de uma sala e comprovou-se que os modelos de propagação que foram estendidos à faixa de UHF podem ser empregados com precisão para se determinar o nível de recepção do sinal de TV digital.This work presents an analysis of signal propagation of Digital TV on the UHF range in indoor environments. Based on the comparison of some indoor and outdoor propagation models described on the literature, an algorithm was developed with the aim of generating a signal coverage map that exhibits the reception power on the indoor environment. These simulations were compared with field measurements divided in two case studies. The first one evaluates the signal coverage in an entire floor of one building and the second one inside a single room. It was proved that the propagation models that were extended to the UHF range can be used with high accuracy to determine the reception power level of the digital TV signal.

Texto completoResumen
The Libyan media has dramatically changed in recent years. This has been most prominently manifest in the introduction of new satellite television news services. This thesis was designed to investigate two elements – patterns of news media consumption and news credibility in Libya. It examined the patterns of major local and international TV news services operating across different media, broadcast and print, and associations between Libyan students’ consumption of different news media platforms. In this context, it investigated the news consumption habits of young people, with special attention paid to their consumption of pan-Arab news services broadcast via satellite television. It looked at the perception of gratifications students obtained from these news services. It also reported findings on students’ perceptions of the credibility of two local, Al Jamahiriya and Al Libiya TV, and two pan-Arab TV news services, Al Jazeera and Al Arabiya. In order to address the thesis research questions, a survey was administered to a sample of 400 undergraduate students at Al-Fateh University using a stratified random sampling approach, with the sampling strata set by demographic variables. The study found that the new TV news services played an important role in attracting young Libyans with information they desire. The spread of new news media sources (television, radio and print) in Libya has created a new type of customer that transcends national boundaries. Statistical analyses indicated that there are distinct news consumption demographic differences defined in part by news platform (TV versus radio versus print) and in part by the type of news provider (local versus non-local TV news services). The findings were discussed in relation to the growing impact of international satellite broadcast news services and the need for local TV news services to find methods of making themselves distinctive in a way that provides an alternative but still relevant and valued news sources. With regard to news credibility, in general Al Jazeera and Al Arabiya were given higher credibility scores than Al Jamahiriya and Al Libiya news services. Higher credibility ratings, however, were significantly correlated with an increased likelihood of reported watching of both local TV news services, but only one of the pan-Arab TV news services (Al Jazeera).

O presente trabalho tem como objetivo central analisar historicamente as discussões e iniciativas envolvidas na constituição de modelos de TV cultural-educativa e/ou pública no Brasil durante o período de 1960 a 1974, tendo como eixo norteador o estudo histórico das relações que tornaram possível a TV Cultura, canal 2, de São Paulo, quer em sua fase como emissora privada, quer como tevê pública. Dessa forma, esta pesquisa de mestrado tem como intento trazer a lume dados e análises que permitam comprovar a hipótese de que as definições e as iniciativas, tanto da ordem privada como governamental, voltadas para a TV como serviço público e veículo cultural-educativo se mostram limitadas e frágeis. Limitadas em razão delas se restringirem inicialmente ao âmbito dos agentes atuantes no campo da comunicação social, portanto, sem amplitude social, e posteriormente serem encapadas pelo Estado brasileiro em momento de acentuado autoritarismo. Frágil por que não permitiram instrumentos e mecanismos para engendrar uma diretriz de programação consistente à televisão educativa que lhe possibilitasse, ao mesmo tempo, significativa aderência da audiência e graus considerados de autonomia na sua condução. Nesta direção, esta pesquisa analisa a formação e o desenvolvimento do campo televisivo brasileiro e as visões e interesses da imprensa impressa sobre este, mais especificamente dos periódicos O Estado de S. Paulo, Diário de São Paulo e O Cruzeiro. Pontua o debate e as iniciativas voltadas para a elaboração de representações e práticas ocupadas com o modelo de televisão cultural-educativa e/ou pública durante o período de 1960 a 1974, advindas de instituições, movimentos e grupos do campo político, social...
This current dissertation has as central objective to analyse historically discussions and initiatives that are involved in constitutions of models of public and/or cultural-educational TV in Brazil during the period from 1960 to 1974, having as orientate axle the historical study of relations which become possible the TV Cultura, channel 2, of São Paulo, either in its phase as private broadcasting station, or as public TV. So, this research of master´s degree has the aim to bring the light data and analyses that can prove the hypotheses of what the definitions and the initiatives, as the private order as governmental one, turned to a like a public service and cultural-educational means show limited and fragile. Limited in reason to restrict initially to the active agents level in the social communication field, so, without social amplitude, and subsequently to be adopted by Brazilian State in moment of marked authoritarian. Fragile because they didn´t allow instruments and mechanisms to dream up a directive of consistent programming to educational television that can be possible, as the same time, significant adherent to audience and considered rates of autonomy in its conduction. In this direction, this research analyses the formation and development of Brazilian TV field and views and interests of pressed media on this one, more specifically of newspaper such as O Estado de S.

Um dos principais desafios da TV Unesp, emissora da Universidade Estadual Paulista “Júlio de Mesquita Filho” – Unesp, é ser vista por diferentes segmentos de públicos para além da cidade de Bauru/SP, local onde opera em sistema de TV aberta. Considerando que a Unesp é uma instituição multicampi, as ações voltadas a dar visibilidade aos conteúdos da emissora encontram nos sites de redes sociais importantes ferramentas de divulgação. Partindo da compreensão da trajetória das TVs universitárias no Brasil, das especificidades da TV Unesp e dos desafios da busca pela audiência deste segmento no ecossistema midiático contemporâneo, marcado por novas possibilidades advindas da digitalização, buscou-se analisar de que modo um site de rede social como o Facebook constitui um efetivo aliado neste propósito. Sob o olhar da sociossemiótica, abordagem teórico-metodológica para análise das estratégias de visibilidade adotadas pela TV Unesp, foi possível identificar como a emissora tem atuado frente a públicos segmentados num processo de ajustamento, nos termos propostos por Eric Landowski (2014). Adotando-se o critério de efetividade das publicações analisadas, observouse que embora a emissora utilize o Facebook para promover e divulgar seus conteúdos televisivos, as estratégias e ações realizadas não configuram um planejamento que direcione com clareza a busca de posicionamento frente aos seus públicos de interesse no contexto midiático.
One of the main challenges for the Unesp TV, Unesp – Universidade Estadual Paulista “Júlio de Mesquita Filho” ‘s network, is to be seen by different public segments beyond the city of Bauru/SP, place where it operates in an open broadcast TV system. Considering that Unesp is a multi-campus institution, the actions towards giving visibility to the contents of the network are found in social networks websites which are important promoting tools. Using as a start point the comprehension of the Universities TV’s trajectory in Brazil, the specificities of UNESP TV and the challenges in search for audience in this segment of the contemporary mediatic ecosystem, it is marked by new possibilities deriving from digitalization, it was seeked to analyze how a social network website like Facebook constitutes an effective ally in this purpose. Through the view of social semiotics, a theoretic-methodologic approach for the visibility strategies analysis taken by UNESP TV, it was possible to identify how the network has faced the segmented publics in an adjustment process, in the terms proposed by Eric Landowski (2014). Taking the publications analyzed effectiveness criteria, it was observed that although the network uses Facebook to promote and diffuse its television’s content, the strategies and actions made don’t meet a planning that directs with clarity the search of positioning with their interest publics in the mediatic context.

Previous issue date: 2014-08-07This master thesis presents the proposal of assigning the cognitive ability to a gap filler. Differently from the usual repeaters found on the market, the adaptive gap filler is able to automatically monitor tuned channels with the intention of verifying if the protection ratio described in Resolution nº398 from Anatel is being respected. Spectrum sensing techniques and the concepts related to coverage area will be addressed. Tests were carried out on the Matlab and GNU Radio Software with the purpose of analyzing the adaptive gap filler performance on real channels.
Este trabalho apresenta a proposta de atribuir ao gap filler a capacidade cognitiva . Diferentemente dos repetidores encontrados no mercado, o gap filler adaptativo tem como função monitorar, de forma autônoma, os canais sintonizados para verificar se a relação de proteção descrita na Resolução nº 398 da Anatel está sendo respeitada. Como fundamentos dessa proposta são abordadas as técnicas de sensoriamento do espectro e os conceitos relacionados às áreas de cobertura. Em uma abordagem prática, os testes foram desenvolvidos no Matlab e no GNU Radio, em que se analisa a atuação do gap filler adaptativo em canais reais.

Como alguém se torna o que é? Qual a contribuição de uma TV universitária para a constituição de um fazer jornalístico? De que modos o estudante se torna um agrônomo, um historiador, um engenheiro, um jornalista? É a partir de questões como essas, ligadas à formação na Universidade, que a presente tese é construída. O fio condutor da pesquisa e de toda a elaboração teórica se faz em torno do programa Universidade: a vida é mais, produzido em uma televisão universitária; nele, quatro estudantes de jornalismo e quatro estudantes de outros cursos de graduação se encontram para falar de suas trajetórias acadêmicas e de muitas outras experiências, para além da vida universitária. O Programa se dispõe a uma escuta do outro, aberto ao que o diferente tem a dizer, como forma de propor modos de pensar a formação acadêmica, técnica, pessoal e cidadã de futuros profissionais. A partir de contribuições teóricas de autores como Michel Foucault, Rosa Maria Bueno Fischer, Carlos Skliar e Jorge Larrosa, pensamos como se dão os processos de transformação dos estudantes, por meio de narrativas de si, dos movimentos do próprio pensamento e da experiência de alteridade, construída no ambiente universitário. São analisados dez episódios do Programa, com foco na multiplicidade de olhares dos oito estudantes; metodologicamente, faz-se na tese um trabalho ensaístico, que busca, numa interlocução entre arte e ciência, modos de potencializar os estudantes como narradores, tanto da própria existência quanto das vidas dos demais. Ao lado de um aprendizado de práticas do jornalismo, da engenharia ou da agronomia, os participantes do Programa expõem as diferentes escolhas na criação de seus modos de constituir-se como cidadãos, pais e mães, amigos e amigas, pesquisadores e profissionais, investindo num desejo de, permanentemente, tornarem-se diferentes do que são. O estudo evidencia, ainda, de modo mais amplo, que talvez a grandeza de uma universidade estaria em que ela pode mais: há uma potência na vida acadêmica, no sentido de outras possibilidades de formação, que invistam nas coisas mínimas, em práticas nas quais tudo o que sucede aos jovens interessa, como matéria simultaneamente de saberes, artes da existência e constituição ética.How does one become what it is? What is the contribution of a university TV to the constitution of a journalistic work? In what ways does the student become an agronomist, a historian, an engineer, a journalist? It is from questions such as these, linked to the formation at the University, that the present thesis is constructed. The guiding thread of the research and of all the theoretical elaboration is made around the program University: the life is more, produced in a university television; four journalism students and four undergraduate students meet to talk about their academic trajectories and many other experiences beyond university life. The Program is prepared to listen to the other, open to what the different has to say, as a way of proposing ways of thinking the academic, technical, personal and citizen training of future professionals. Based on the theoretical contributions of authors such as Michel Foucault, Rosa Maria Bueno Fischer, Carlos Skliar and Jorge Larrosa, we think about the processes of student transformation through narratives of oneself, the movements of one's own thinking and the experience of otherness, built in the university environment. Ten episodes of the Program are analyzed, focusing on the multiplicity of looks of the eight students; methodologically, the thesis is an essayist work, which seeks, in an interplay between art and science, ways of empowering students as narrators, both of their own existence and of the lives of others. In addition to an apprenticeship in journalism, engineering or agronomy practices, Program participants expose the different choices in creating their ways of becoming citizens, parents, friends, researchers and practitioners by investing in permanent desire to become different from what they are. The study also shows more broadly that perhaps the greatness of a university is that it can do more: there is a power in the academic life, in the sense of other possibilities of formation, that invest in the minimum things, in practices in which everything that happens to young people matters as a matter simultaneously of knowledge, art of existence and ethical constitution.

The study sought to investigate the use of RFID technology as inventory control in academic libraries in South Africa, with a focus on the University of South Africa and the University of Fort Hare libraries. The objectives of the study were to describe the current inventory control practices at the libraries of the University of South Africa and the University of Fort Hare in order to determine the infrastructure required for the use of RFID for inventory control for the University of Fort Hare’s libraries; to evaluate the benefits of RFID technologies, in order to gain a competitive advantage for the University of South Africa’s and the University of Fort Hare’s libraries; to identify the challenges associated with adopting RFID technology, as experienced by the libraries of the University of South Africa and the University of Fort Hare. The study adopted both the quantitative and qualitative research approaches. The researcher followed a rigorous methodological path that began with a thorough literature review coupled with the careful and thoughtful posing of research questions and objectives. A purposive sample of forty (40) respondents was selected from the library staff from both the University of South Africa and University of Fort Harelibraries. The collected data were analysed using the Statistical Package for Social Sciences 23 (SPSS 23) and Microsoft Excel 2010. The findings of the study revealed reasons for both academic libraries to invest in RFID technology; these reasons include RFID’s ability to deliver self-service options, inventory control, improved reader access and improved security. The challenges related to the implementation of RFID technology are also related to staff not being rewarded by library management for being innovative; the difficulty of staff learning new technology; the staff’s inability to generate new ideas for the library; and the staff not being able to share knowledge with each other. Further research needs to be conducted by library RFID vendors in order to meet the need, of academic libraries, for RFID inventory control. RFID hardware and software (API software) should be subjected to further investigation for the purposes of research and development. Libraries should work closer with RFID vendors so as to trial and test hardware and software.

Texto completoResumen
Abstract The aims of the present study were to clarify the antenna function and radio frequency radiation (RFR) sensitivity of human subjects using theoretical calculations and field tests. The weak very high frequency (VHF) electromagnetic fields and spontaneous hand movements were recorded. Groups of university students, other volunteers and as a very interesting group, experienced well finders, were used as test subjects. The VHF field was studied using a spectrum analyser and tuneable narrow-band or broad-band meter with a dipole antenna. The hand movements were registered by potentiometric systems and electromyography (EMG). The test subjects (altogether n = 140) in different tests were walking, sitting in a cart being pulled slowly forward, or sitting in a moving car. The responses were observed and hand movements were recorded and analysed by personal computers. By visual inspection and using the Pearson's correlation, the results of different individuals have been compared with the measured intensity of far fields of a radio mast. Reaction spots and graphs defined by different individuals in the same experiment areas have been compared to each other. Hand movement correlated with the reactions of the forearm and shoulder muscles, e.g., pronator teres and trapezius, by EMG measurements. The reactions of some persons correlated with each other. Experiments in a slow moving wagon and in a moving car showed a correlation between the test subjects’ hand movements and the intensity of below 1 mV/m radio and TV signals measured in the vicinity of the test subject. In open field tests different persons usually reacted in widely different ways. The most evident results were recorded near the buildings, where the radio waves reflected from the wall and patterns of standing waves were clear. Many VHF frequency modulated (FM) broadcasting signals were summed at these places at the same time. It is concluded that the spontaneous hand movement reactions occurred as a response of the human body to the gradients of the VHF field intensity. The reaction generally occurred in interference patterns of multipath propagation or standing waves originating from the radiation of FM radio and TV broadcasting transmitters and radiation reflected from the walls of buildings or from other objects. This non-thermal reaction was clearly observable as spontaneous arm movements by 39 percent of the 85 tested studentsTiivistelmä Tässä tutkimuksessa selvitettiin ihmisen herkkyyttä radiotaajuiselle säteilylle. Ihmisen toimimista radioaaltojen antennina tarkasteltiin teoreettisesti ja kenttäkokein. Heikkojen VHF-alueen radioaaltojen voimakkuutta ja tahattomia käsien liikkeitä rekisteröitiin valituilla koepoluilla. Koehenkilöinä on ollut yliopiston opiskelijoita ja muita vapaaehtoisten ryhmiä. Kiinnostavin ryhmä oli kokeneet kaivonkatsojat, joiden käsienliikereaktioihin radioaaltojen vaikutuksista löytyy viitteitä kirjallisuudesta. Radioaaltojen voimakkuuden vaihteluja mitattiin spektrianalysaattorilla ja laajakaistaisella VHF-alueen integroivalla mittarilla. Käsien liikkeitä rekisteröitiin potentiometriin perustuvilla liikeantureilla. Lihasten sähköimpulsseja rekisteröitiin elektromyografia- eli EMG-laitteella. Eri koesarjoissa koehenkilöt (yhteensä 140) kävelivät, istuivat hitaasti vedettävässä vaunussa tai istuivat liikkuvassa autossa. Reaktioita tarkkailtiin ja käsien liikkeet ja mitatut kentänvoimakkuudet rekisteröitiin ja analysoitiin tietokoneella. Eri koehenkilöiden tuloksia, reagointipaikkoja ja rekisteröityjä käyriä 5–35 km:n etäisyydellä mastoista tarkasteltiin silmämääräisesti. Pearsonin korrelaatiolaskentaa apuna käyttäen tuloksia verrattiin radiomastojen säteilyn voimakkuuteen. Eri ihmisten reagointikohtia ja käyriä samoilta koealueilta vertailtiin keskenään. Koeasetelmassa käsienliikkeiden todettiin korreloivan joidenkin kyynärvarren ja hartialihasten (mm. pronator teres ja trapezius) EMG-signaaleihin. Joidenkin koehenkilöiden tulokset korreloivat keskenään. Hitaasti vedettävässä vaunussa ja liikkuvassa autossa tehdyissä kokeissa tuli esille korrelaatio vartalon edessä olevien käsien loittonemis-lähestymis-liikkeiden ja koehenkilön välittömässä läheisyydessä mitattujen 1 mV/m -tasoisten radio- ja TV-signaalien voimakkuusvaihtelujen välillä. Avoimella kentällä henkilöt reagoivat hyvin eri tavoin. Parhaiten yhteys tuli esille rakennusten lähellä sijaitsevilla koealueilla, joissa radioaallot heijastuivat rakennuksen seinästä muodostaen selkeitä seisovan aallon kuvioita. Useat taajuusmoduloidut VHF-alueen radiosignaalit summautuivat näissä paikoissa samanaikaisesti. Johtopäätöksenä on, että tahattomat käsienliikkeet tapahtuvat kehon vasteena VHF-kentän voimakkuuden muutoksille. Reaktio tapahtui yleensä interferenssi-kuvioissa tai seisovissa aalloissa, jotka muodostuvat FM-radio- ja TV-lähetysten monitie-etenemisestä radioaaltojen heijastuessa rakennusten seinistä tai muista kohteista. Tämä ei-lämpövaikutustason reaktio oli selvästi havaittavissa olkapään tasalle koukistetun käden tahattomana ojennus-koukistus-liikkeenä 39 prosentilla testatuista 85 opiskelijasta
