The emotional structure of the advertising message in radio

Radio advertising is suffering from a remarkable crisis of creativity as it has yet not found its role in a radio model based on voice locution and information genres. This article suggests the need for implementing a peripheral or heuristic strategy to attract and hold listeners’ attention. Within this framework, the narration and scene representation are proposed as suitable persuasion techniques. The objective is to design a useful conceptual tool for an efficient creative conception of narration at the service of certain commercial strategy. First, the concept of narrative persuasion is grounded according to the possibilities of the sound code. Second, the keys of scene representation and commercial strategy (brand, product, advantage, benefit and target) within the sound message are presented. And third, these keys are articulated in a model. This model is pre-tested by means of analyzing eight different case-radio ads.

Citizens’ attitudes toward public services. Satisfaction in 2009-2011

The aim of this paper is to study the recent changes on citizens’ satisfaction with the performance ofpublic services, in the period 2009-2011 in Spain. Using data from the surveys on Quality of PublicServices, developed by the Sociological Research Center jointly with the National Agency for theEvaluation of Public Services and Quality of Services, our results show that the level of satisfactionhas slightly increased, which seems to display a greater tendency to positively value public servicesduring economic retrenchment. A major determinant of high satisfaction is self-reported ideology.Besides, immigrants display higher levels of satisfaction than Spaniards.

Citizens as Social Work Educators in a Post-Conflict Society: Reflections from Northern Ireland

ABSTRACT This paper examines how service users and carers can contribute to social work education in a post conlict society. A small-scale study undertaken in Northern Ireland is used as a case study to show how such citizens can potentially critically contribute to social work students’ understanding of the impact of conlict on individuals, groups and communities. The need to appreciate the effects of such community division is now a core knowledge requirement of the social work curriculum in Northern Ireland. The article reports on research indings with service users, carers and agency representatives which points to ways in which social work students can achieve a critical understanding of the impact of conlict. Northern Ireland, in this way, is presented as a divided society, still in a state of adjustment and evolution, following a period of protracted community strife and violence. The author suggests that individuals who have been directly affected by conlict can contribute in an informed and critical way to social work students’ developing knowledge and experience in an important area of their professional competence and understanding of anti-oppressive practice more broadly.

Novel Radio Link Buffer Management Schemes for End-User Multi-class Traffic in High Speed Packet Access Networks

The requirement to provide multimedia services with QoS support in mobile networks has led to standardization and deployment of high speed data access technologies such as the High Speed Downlink Packet Access (HSDPA) system. HSDPA improves downlink packet data and multimedia services support in WCDMA-based cellular networks. As is the trend in emerging wireless access technologies, HSDPA supports end-user multi-class sessions comprising parallel flows with diverse Quality of Service (QoS) requirements, such as real-time (RT) voice or video streaming concurrent with non real-time (NRT) data service being transmitted to the same user, with differentiated queuing at the radio link interface. Hence, in this paper we present and evaluate novel radio link buffer management schemes for QoS control of multimedia traffic comprising concurrent RT and NRT flows in the same HSDPA end-user session. The new buffer management schemes—Enhanced Time Space Priority (E-TSP) and Dynamic Time Space Priority (D-TSP)—are designed to improve radio link and network resource utilization as well as optimize end-to-end QoS performance of both RT and NRT flows in the end-user session. Both schemes are based on a Time-Space Priority (TSP) queuing system, which provides joint delay and loss differentiation between the flows by queuing (partially) loss tolerant RT flow packets for higher transmission priority but with restricted access to the buffer space, whilst allowing unlimited access to the buffer space for delay-tolerant NRT flow but with queuing for lower transmission priority. Experiments by means of extensive system-level HSDPA simulations demonstrates that with the proposed TSP-based radio link buffer management schemes, significant end-to-end QoS performance gains accrue to end-user traffic with simultaneous RT and NRT flows, in addition to improved resource utilization in the radio access network.

Falls prevention and support:: translating research, integrating services and promoting the contribution of service users for quality and innovative programmes of care

Falls are a significant threat to the safety, health and independence of older citizens. Despite the substantial evidence that is available around effective falls prevention programmes and interventions, their translation into falls reduction programmes and policies has yet to be fully realised. While hip fracture rates are decreasing, the number and incidence of fall-related hospital admissions among older people continue to rise. Given the demographic trends that highlight increasing numbers of older people in the UK, which is broadly reflected internationally, there is a financial and social imperative to minimise the rate of falls and associated injuries. Falling is closely aligned to growing older (Slips, Trips and Falls Update: From Acute and Community Hospitals and Mental Health Units in England and Wales, Department of Health, HMSO, London, 2010). According to the World Health Organization, around 30% of older people aged over 65 and 50% of those over 80 will fall each year (Falls Fact Sheet Number 344, WHO, Geneva, 2010). Falls happen as a result of many reasons and can have harmful consequences, including loss of mobility and independence, confidence and in many cases even death (Cochrane Database Syst Rev 15, 2009, 146; Slips, Trips and Falls Update: From Acute and Community Hospitals and Mental Health Units in England and Wales, Department of Health, HMSO, London, 2010; Falling Standards, Broken Promises: Report of the National
Audit of Falls and Bone Health in Older People 2010, Health Care Quality
Improvement Partnership, London, 2011). What is neither fair nor correct is the
common belief by old and young alike that falls are just another inconvenience to put up with. The available evidence justifiably supports the view that well-organised services, based upon national standards and expert guidance, can prevent future falls among older people and reduce death and disability from fractures. This paper will draw from the UK, as an exemplar for policy and practice, to discuss the strategic direction of falls prevention programmes for older people and the partnerships that need to exist between researchers, service providers and users of services to translate evidence to the clinical setting. Second, it will propose some mechanisms for disseminating evidence to healthcare professionals and other stakeholders, to improve the quality and capacity of the clinical workforce.

The Impact of EU Privacy Legislation on Biometric System Deployment: Protecting citizens but constraining applications

Biometric systems provide a valuable service in helping to identify individuals from their stored personal details. Unfortunately, with the rapidly increasing use of such systems, there is a growing concern about the possible misuse of that information. To counteract the threat, the European Union (EU) has introduced comprehensive legislation that seeks to regulate data collection and help strengthen an individual’s right to privacy. This article looks at the implications of the legislation for biometric system deployment. After an initial consideration of current privacy concerns, it examines what is meant by ‘personal data’ and its protection, in legislation terms. Also covered are issues around the storage of biometric data, including its accuracy, its security, and justification for what is collected. Finally, the privacy issues are illustrated through three biometric use cases: border security, online bank access control and customer profiling in stores.

Multilayer optimization in radio resource allocation for the packet transmission in wireless networks

Na última década tem-se assistido a um crescimento exponencial das redes de comunicações sem fios, nomeadamente no que se refere a taxa de penetração do serviço prestado e na implementação de novas infra-estruturas em todo o globo. É ponto assente neste momento que esta tendência irá não só continuar como se fortalecer devido à convergência que é esperada entre as redes móveis sem fio e a disponibilização de serviços de banda larga para a rede Internet fixa, numa evolução para um paradigma de uma arquitectura integrada e baseada em serviços e aplicações IP. Por este motivo, as comunicações móveis sem fios irão ter um papel fundamental no desenvolvimento da sociedade de informação a médio e longo prazos. A estratégia seguida no projecto e implementação das redes móveis celulares da actual geração (2G e 3G) foi a da estratificação da sua arquitectura protocolar numa estrutura modular em camadas estanques, onde cada camada do modelo é responsável pela implementação de um conjunto de funcionalidades. Neste modelo a comunicação dá-se apenas entre camadas adjacentes através de primitivas de comunicação pré-estabelecidas. Este modelo de arquitectura resulta numa mais fácil implementação e introdução de novas funcionalidades na rede. Entretanto, o facto das camadas inferiores do modelo protocolar não utilizarem informação disponibilizada pelas camadas superiores, e vice-versa acarreta uma degradação no desempenho do sistema. Este paradigma é particularmente importante quando sistemas de antenas múltiplas são implementados (sistemas MIMO). Sistemas de antenas múltiplas introduzem um grau adicional de liberdade no que respeita a atribuição de recursos rádio: o domínio espacial. Contrariamente a atribuição de recursos no domínio do tempo e da frequência, no domínio espacial os recursos rádio mapeados no domínio espacial não podem ser assumidos como sendo completamente ortogonais, devido a interferência resultante do facto de vários terminais transmitirem no mesmo canal e/ou slots temporais mas em feixes espaciais diferentes. Sendo assim, a disponibilidade de informação relativa ao estado dos recursos rádio às camadas superiores do modelo protocolar é de fundamental importância na satisfação dos critérios de qualidade de serviço exigidos. Uma forma eficiente de gestão dos recursos rádio exige a implementação de algoritmos de agendamento de pacotes de baixo grau de complexidade, que definem os níveis de prioridade no acesso a esses recursos por base dos utilizadores com base na informação disponibilizada quer pelas camadas inferiores quer pelas camadas superiores do modelo. Este novo paradigma de comunicação, designado por cross-layer resulta na maximização da capacidade de transporte de dados por parte do canal rádio móvel, bem como a satisfação dos requisitos de qualidade de serviço derivados a partir da camada de aplicação do modelo. Na sua elaboração, procurou-se que o standard IEEE 802.16e, conhecido por Mobile WiMAX respeitasse as especificações associadas aos sistemas móveis celulares de quarta geração. A arquitectura escalonável, o baixo custo de implementação e as elevadas taxas de transmissão de dados resultam num processo de multiplexagem de dados e valores baixos no atraso decorrente da transmissão de pacotes, os quais são atributos fundamentais para a disponibilização de serviços de banda larga. Da mesma forma a comunicação orientada à comutação de pacotes, inenente na camada de acesso ao meio, é totalmente compatível com as exigências em termos da qualidade de serviço dessas aplicações. Sendo assim, o Mobile WiMAX parece satisfazer os requisitos exigentes das redes móveis de quarta geração. Nesta tese procede-se à investigação, projecto e implementação de algoritmos de encaminhamento de pacotes tendo em vista a eficiente gestão do conjunto de recursos rádio nos domínios do tempo, frequência e espacial das redes móveis celulares, tendo como caso prático as redes móveis celulares suportadas no standard IEEE802.16e. Os algoritmos propostos combinam métricas provenientes da camada física bem como os requisitos de qualidade de serviço das camadas superiores, de acordo com a arquitectura de redes baseadas no paradigma do cross-layer. O desempenho desses algoritmos é analisado a partir de simulações efectuadas por um simulador de sistema, numa plataforma que implementa as camadas física e de acesso ao meio do standard IEEE802.16e.

Electronic health records for mobile citizens: a secure and collaborative architecture

Durante as ultimas décadas, os registos de saúde eletrónicos (EHR) têm evoluído para se adaptar a novos requisitos. O cidadão tem-se envolvido cada vez mais na prestação dos cuidados médicos, sendo mais pró ativo e desejando potenciar a utilização do seu registo. A mobilidade do cidadão trouxe mais desafios, a existência de dados dispersos, heterogeneidade de sistemas e formatos e grande dificuldade de partilha e comunicação entre os prestadores de serviços. Para responder a estes requisitos, diversas soluções apareceram, maioritariamente baseadas em acordos entre instituições, regiões e países. Estas abordagens são usualmente assentes em cenários federativos muito complexos e fora do controlo do paciente. Abordagens mais recentes, como os registos pessoais de saúde (PHR), permitem o controlo do paciente, mas levantam duvidas da integridade clinica da informação aos profissionais clínicos. Neste cenário os dados saem de redes e sistemas controlados, aumentando o risco de segurança da informação. Assim sendo, são necessárias novas soluções que permitam uma colaboração confiável entre os diversos atores e sistemas. Esta tese apresenta uma solução que permite a colaboração aberta e segura entre todos os atores envolvidos nos cuidados de saúde. Baseia-se numa arquitetura orientada ao serviço, que lida com a informação clínica usando o conceito de envelope fechado. Foi modelada recorrendo aos princípios de funcionalidade e privilégios mínimos, com o propósito de fornecer proteção dos dados durante a transmissão, processamento e armazenamento. O controlo de acesso _e estabelecido por políticas definidas pelo paciente. Cartões de identificação eletrónicos, ou certificados similares são utilizados para a autenticação, permitindo uma inscrição automática. Todos os componentes requerem autenticação mútua e fazem uso de algoritmos de cifragem para garantir a privacidade dos dados. Apresenta-se também um modelo de ameaça para a arquitetura, por forma a analisar se as ameaças possíveis foram mitigadas ou se são necessários mais refinamentos. A solução proposta resolve o problema da mobilidade do paciente e a dispersão de dados, capacitando o cidadão a gerir e a colaborar na criação e manutenção da sua informação de saúde. A arquitetura permite uma colaboração aberta e segura, possibilitando que o paciente tenha registos mais ricos, atualizados e permitindo o surgimento de novas formas de criar e usar informação clínica ou complementar.

Characterization of RSOA modulators in radio over fiber links

In this work physical and behavioral models for a bulk Reflective Semiconductor Optical Amplifier (RSOA) modulator in Radio over Fiber (RoF) links are proposed. The transmission performance of the RSOA modulator is predicted under broadband signal drive. At first, the simplified physical model for the RSOA modulator in RoF links is proposed, which is based on the rate equation and traveling-wave equations with several assumptions. The model is implemented with the Symbolically Defined Devices (SDD) in Advanced Design System (ADS) and validated with experimental results. Detailed analysis regarding optical gain, harmonic and intermodulation distortions, and transmission performance is performed. The distribution of the carrier and Amplified Spontaneous Emission (ASE) is also demonstrated. Behavioral modeling of the RSOA modulator is to enable us to investigate the nonlinear distortion of the RSOA modulator from another perspective in system level. The Amplitude-to-Amplitude Conversion (AM-AM) and Amplitude-to-Phase Conversion (AM-PM) distortions of the RSOA modulator are demonstrated based on an Artificial Neural Network (ANN) and a generalized polynomial model. Another behavioral model based on Xparameters was obtained from the physical model. Compensation of the nonlinearity of the RSOA modulator is carried out based on a memory polynomial model. The nonlinear distortion of the RSOA modulator is reduced successfully. The improvement of the 3rd order intermodulation distortion is up to 17 dB. The Error Vector Magnitude (EVM) is improved from 6.1% to 2.0%. In the last part of this work, the performance of Fibre Optic Networks for Distributed and Extendible Heterogeneous Radio Architectures and Service Provisioning (FUTON) systems, which is the four-channel virtual Multiple Input Multiple Output (MIMO), is predicted by using the developed physical model. Based on Subcarrier Multiplexing (SCM) techniques, four-channel signals with 100 MHz bandwidth per channel are generated and used to drive the RSOA modulator. The transmission performance of the RSOA modulator under the broadband multi channels is depicted with the figure of merit, EVM under di erent adrature Amplitude Modulation (QAM) level of 64 and 254 for various number of Orthogonal Frequency Division Multiplexing (OFDM) subcarriers of 64, 512, 1024 and 2048.

Defining the nation, defining public television: discourses of publics on public service television in post-communist Latvia

Institutional and political economy approaches have long dominated the study of post-Communist public broadcasting, as well as the entire body of post-Communist media transformations research, and the enquiry into publics of public broadcasting has traditionally been neglected. Though media scholars like to talk about a deep crisis in the relationship between public broadcasters and their publics in former Communist bloc countries across Central and Eastern Europe, little has been done to understand the relationship between public broadcasters and their publics in these societies drawing on qualitative audience research tradition. Building on Hirschman’s influential theory of ‘exit, voice and loyalty’, which made it possible to see viewing choices audiences make as an act of agency, in combination with theoretical tools developed within the framework of social constructionist approaches to national imagination and broadcasting, my study focuses on the investigation of responses publics of the Latvian public television LTV have developed vis-à-vis its role as contributing to the nation-building project in this ex-Soviet Baltic country. With the help of focus groups methodology and family ethnography, the thesis aims to explore the relationship between the way members of the ethno-linguistic majority of Latvian-speakers and the sizeable ethno-linguistic minority of Russian-speakers conceptualize the public broadcaster LTV, as well as understand the concept of public broadcasting more generally, and the way they define the national ‘we’. The study concludes that what I call publics of LTV employ Hirschman’s described exit mechanism as a voice-type response. Through their rejection of public television which, for a number of complex reasons they consider to be a state broadcaster serving the interests of those in power they voice their protest against the country’s political establishment and in the case of its Russian-speaking publics also against the government’s ethno-nationalistic conception of the national ‘we’. I also find that though having exited from the public broadcaster LTV, its publics have not abandoned the idea of public broadcasting as such. At least at a normative level the public broadcasting ideals are recognized, accepted and valued, though they are not necessarily associated with the country’s de jure institutional embodiment of public broadcasting LTV. Rejection of the public television has also not made its non-loyal publics ‘less citizens’. The commercial rivals of LTV, be they national or, in the case of Russian-speaking audiences, localized transnational Russian television, have allowed their viewers to exercise citizenship and be loyal nationals day in day out in a way that is more liberal and flexible than the hegemonic form of citizenship and national imagination of the public television LTV can offer.

Good Practice in EU Public Service Media and Contemporary Practice in Jordan: A Comparative Analysis

UNESCO Amman Office Foreword: UNESCO Amman office is pleased to publish a comparative analysis between good Public Service Media (PSM) practices in Europe and the contemporary practice in Jordan. The study is part of the Support to Media in Jordan project, funded by the European Union, aiming to increase media freedom, media independence and journalistic professionalism in Jordan. The state owned broadcaster, Jordan Radio and Television (JRTV), has informed, entertained and educated Jordanians for decades. JRTV reaches almost every corner of the Kingdom and has the potential to serve all Jordanians with balanced, impartial and accurate news and programmes relevant to their day-to-day lives.Based on this potential there has been a long standing ambition to transform the JRTV from a state broadcaster to a public service broadcaster; from a TV and radio that predominately serves the state, to a broadcaster that serves the public and is independent from the Government of the day. This ambition is expressed also in the Support to Media in Jordan project, agreed between the Government an the EU, under which UNESCO has been asked to produce two studies: The comparative PSM analysis and a broader media landscape assessment based on UNESCO’s Media Development Indicators (MDI’s). The Jordanian MDI assessment was carried out by a team of national and international researchers during the first six months of 2015, and builds on the rich flora of recent studies on the Jordanian media landscape, as well as on original research. The study is available in Arabic and English. Professor Naomi Sakr carried out the comparative PSM analysis parallel to the MDI study, and in close cooperation with the MDI research team and UNESCO Amman office.

"Ici la Suisse-Do isch t Schwyz-Switzerland calling!" : la société suisse de radiodiffusion (SSR) au service du rayonnement culturel helvetique (1932-1949)

La dialectique entre radiodiffusion et histoire des relations culturelles internationales est un domaine largement inexploré. L'objectif de cette thèse est d'analyser le rôle de la Société suisse de radiodiffusion (SSR), société privée qui exerce jusqu'en 1983 le monopole sur l'ensemble des stations de radio suisses, dans l'intensification des relations culturelles internationales de la Confédération. Pour examiner cette dimension des activités de la SSR, je me suis prioritairement penchée sur l'étude de la radio internationale helvétique, dénommée alors « Service suisse d'ondes courtes » (SOC). A l'instar de plusieurs organismes similaires à l'étranger, le SOC remplit dès ses débuts une double mission : resserrer les liens avec la diaspora et faire rayonner le pays hors des frontières nationales. Cette recherche met sur le devant de la scène un acteur médiatique aujourd'hui totalement oublié, le Service suisse d'ondes courtes. Par rapport à l'historiographie des radios internationales, elle mêle approche institutionnelle et, dans la mesure des sources disponibles, l'analyse de la programmation. Elle complète aussi l'histoire de la diplomatie culturelle suisse en rappelant la place du service public audiovisuel parmi les institutions chargées de promouvoir le pays à l'étranger. Pour finir, cette étude constitue également un apport à l'histoire des organisations internationales liées à la radiodiffusion (UIR, UIT). L'analyse du volet international des activités de la SSR a permis de dépasser la seule notion de « puissance » qui a été jusqu'à ces dernières années au coeur des ouvrages dévolus aux radios internationales. L'objectif poursuivi par la SSR ne réside pas tellement dans la diplomatie d'influence (l'exercice d'un « soft power »), qui tend à imposer ses valeurs et un mode de vie, mais plutôt dans la volonté de faire comprendre et reconnaître la culture politique de la Suisse dans le but de renforcer et pérenniser la place de celle-ci dans le concert des nations. Dans cette perspective, la culture devient un moyen utilisé pour transmettre à l'étranger une représentation valorisante du pays, une image de marque (une forme de « Nation Branding » avant l'heure) également utile au secteur touristique et à l'industrie d'exportation. Le Service suisse d'ondes courtes fait ainsi avant tout des relations publiques, un avant-goût de ce que les Américains appelleront dans les années 1960 la « public diplomacy »

Participación política a través de acciones constitucionales. Estudio de caso: matrimonio para personas del mismo sexo en Colombia

El interés de esta investigación se centra en analizar el rol protagónico que han adquirido las acciones constitucionales en la participación política de la comunidad LGTBI, encaminada a la aprobación del matrimonio igualitario en Colombia, a partir de la promulgación de la Constitución Política de 1991. Para este propósito, el estudio presenta un diagnóstico sobre las falencias y limitaciones que ha presentado la representación política y de los mecanismos de participación ciudadana para solventar las reivindicaciones de las parejas del mismo sexo. En consecuencia, la investigación evidencia de qué manera la sub-representación de los intereses de esta comunidad en el Congreso de la República y la sub-utilización de los mecanismos de participación política causadas por las deficiencias en su diseño e implementación, impulsaron a la población LGTBI y los defensores de sus derechos a canalizar su participación política a través de la presentación de acciones constitucionales.

A conceptual life event framework for government-to-citizen electronic service provision

In recent years, life event approach has been widely used by governments all over the world for designing and providing web services to citizens through their e-government portals. Despite the wide usage of this approach, there is still a challenge of how to use this approach to design e-government portals in order to automatically provide personalised services to citizens. We propose a conceptual framework for e-government service provision based on life event approach and the use of citizen profile to capture the citizen needs, since the process of finding Web services from a government-to-citizen (G2C) system involves understanding the citizens’ needs and demands, selecting the relevant services, and delivering services that matches the requirements. The proposed framework that incorporates the citizen profile is based on three components that complement each other, namely, anticipatory life events, non-anticipatory life events and recurring services.
