A Comunicação Interna Corporativa em Rede - Estudo de Caso: A Intranet como instrumento de Gestão Participativa no Grupo EDP

Quer seja a nível pessoal quer seja empresarial existem atualmente muitas formas de obter informações e conhecimentos. Numa empresa são produzidas milhares de informações que causam impacto na vida dos colaboradores, mas que nem sempre são bem comunicadas. O mais importante nos dias de hoje é a mobilidade e o acesso fácil à tecnologia de informação. Até ao final da década de 80, do século XX, a comunicação nas empresas era realizada através dos meios tradicionais, como por exemplo, as publicações impressas, a correspondência empresarial, entre outros. Em pleno século XXI, a comunicação organizacional utiliza também as novas tecnologias de comunicação como meio e instrumento para atingir os seus objetivos. A Intranet é neste momento, o meio de comunicação interna mais utilizado, possibilitando que as informações sejam encontradas e utilizadas de forma mais rápida, e disponibilizadas para todos os membros da organização. Representa um mecanismo que agiliza os processos internos e externos de uma empresa, possibilitando que várias pessoas planeiem estratégias, discutam projetos, realizem reuniões virtuais, de forma a obterem uma relação custo/benefício mais eficiente. A Intranet fornece serviços de correio, web, chat, o que agiliza os processos comunicacionais corporativos, e torna mais eficiente e eficaz a comunicação entre as pessoas e entre os departamentos/áreas de uma organização. Neste sentido a Comunicação Interna tem uma função muito importante, no sentido de fazer circular novas informações, promover o debate e a interação entre os vários colaboradores da organização da mesma área/departamento ou de áreas diferentes e, sobretudo, formar os colaboradores para os novos desafios. Por se tratar de um instrumento muito recente e existir poucos estudos sobre o mesmo e a sua implicação na comunicação interna, esta dissertação poderá ser útil em vários domínios. Ao longo da sua apresentação, e em concreto na revisão da literatura é abordado o conceito de comunicação interna a nível organizacional assim como as variáveis que está intimamente relacionada, e numa segunda fase é abordado a evolução das tecnologias ao serviço da gestão empresarial, e mais em concreto a ferramenta de comunicação- a Intranet. A dissertação tem como objetivo geral perceber que contributo a tecnologia e os novos sistemas de informação, neste caso a utilização da Intranet traz ao Grupo EDP, face às suas políticas de comunicação interna, e em que medida a sua utilização implica o conhecimento e a informação em todos os membros da organização e de que forma isso se expressa. Por um lado, pretende-se percecionar em que medida é que os conteúdos disponibilizados vão de encontro às necessidades e expectativas dos colaboradores e, por outro, percecionar se a informação disponibilizada na intranet da EDP (edpON), por conteúdos temáticos, vai ao encontro das expetativas das diferentes categorias profissionais em que se inserem os seus colaboradores. Este estudo de caso realizado no Grupo EDP, permite analisar sobretudo como a existência de uma Intranet apoia a comunicação interna de uma organização, mobilizando os colaboradores para o aumento do trabalho em equipa e a melhoria do seu desempenho profissional, bem como contribui para uma eficaz gestão comunicacional ao serviço da gestão do grupo empresarial, objeto de estudo. A Comunicação interna no caso do grupo EDP a nível mundial deve permitir compartilhar a missão, a visão, a estratégia e os valores organizacionais. Ela deve cumprir uma função estratégica dentro da empresa, e incorporar o desafio diário da gestão da mudança e ao mesmo tempo espelhar uma cultura organizacional comprometida com metas, objetivos, desempenho e resultados. A importância da concretização deste estudo de caso, no âmbito da análise da comunicação interna e essencialmente da sua Intranet, pretende acrescentar valor à prossecução do cumprimento de objetivos comunicacionais do grupo EDP, assim como propor outras soluções, para a sua gestão empresarial.

Spectacular Disappearances : Celebrity and Privacy, 1696-1801 /

How can the modern individual control his or her self-representation when the whole world seems to be watching? This question is a familiar one amid the the twenty-first century's architecture of 24-hour newsrooms, chat rooms and interrogation rooms, but this book traces this question back to the stages, the pages, and the streets of eighteenth-century London--and to the strange and spectacular self-representations performed there by England's first modern celebrities. These self-representations include the enormous wig that the actor, manager, and playwright Colley Cibber donned in his most famous comic role as Lord Foppington--and that later reappeared on the head of Cibber's cross-dressing daughter, Charlotte Charke. They include the black page of 'Tristram Shandy,' a memorial to the parson Yorick (and his author Laurence Sterne), a page so full of ink that it cannot be read. And they include the puffs and prologues that David Garrick used to hiehgten his publicity while protecting his privacy; the epistolary autobiography, modeled on the sentimental novel, of Garrick's protégée George Anne Bellamy; and the elliptical poems and portraits of the poet, actress, and royal courtesan Mary Robinson, known throughout her life as Perdita. Linking all of these representations is a quality that Fawcett terms "over-expression." 'Spectacular Disappearances' theorizes over-expression as the unique quality that allows celebrities to meet their spectators' demands for disclosure without giving themselves away. Like a spotlight so brilliant it is blinding, these exaggerated but illegible self-representations suggest a new way of understanding some of the key aspects of celebrity culture, both in the eighteenth century and today. They also challenge many of the disciplinary divides between theatrical character and novelistic character in eighteenth-century studies, or between performance studies and literary studies today. Drawing on a wide variety of materials and methodologies, 'Spectacular Disappearances' provides an overlooked but indispensable history for scholars and students of celebrity studies, performance studies, and autobiography--as well as to anyone curious about the origins of the eighteenth-century self.

Retention, adherence and compliance: Important considerations for home- and group-based resistance training programs for older adults

Reports on the efficacy of physical activity intervention trials usually only include discussion of the primary outcomes. However, assessing factors such as participant retention, adherence and compliance can assist in the accurate interpretation of the overall impact of a program in terms of reach and appeal. A quasi-randomised trial was carried out to assess and compare retention and adherence rates, and compliance with, a twice weekly resistance training program provided either individually at home or in a group format. Retirement villages (n=6) were assigned to either 'Have A Try' (HAT, home-based) or 'Come Have A Try' (CHAT, group-based); both programs included nine strength and two balance exercises. The program involved a 20-week Intervention Phase a 24-week Maintenance Phase and a 20-week On-going Maintenance Phase. One hundred and nineteen participants (mean age 80 +/- 6 years) were recruited (HAT = 38, CHAT = 81). There was no difference in retention rates at the end of the Intervention Phase, but significantly more HAT than CHAT participants had dropped out of the study (p < 0.01) after the Maintenance Phase and the On-going Maintenance Phase. During the Intervention Phase, over half the HAT and CHAT participants completed >= 75% of the prescribed activity sessions, but adherence was significantly greater in CHAT than HAT during the Maintenance Phase (p < 0.01). Participants in CHAT were significantly more compliant than HAT participants (p < 0.05). Both home- and group-based formats were successful over the short-term, but, in retirement villages, the group program had better adherence and compliance in the longer-term.

Linkage analyses of event-related potential slow wave phenotypes recorded in a working memory task

Working memory is an essential component of wide-ranging cognitive functions. It is a complex genetic trait probably influenced by numerous genes that individually have only a small influence. These genes may have an amplified influence on phenotypes closer to the gene action. In this study, event-related potential (ERP) phenotypes recorded during a working-memory task were collected from 656 adolescents from 299 families for whom genotypes were available. Univariate linkage analyses using the MERLIN variance-components method were conducted on slow wave phenotypes recorded at multiple sites while participants were required to remember the location of a target. Suggestive linkage (LOD > 2.2) was found on chromosomes 4, 5, 6, 10, 17, and 20. After correcting for multiple testing, suggestive linkage remained on chromosome 10. Empirical thresholds were computed for the most promising phenotypes. Those on chromosome 10 remained suggestive. A number of genes reported to regulate neural differentiation and function (i.e. NRP1, ANK3, and CHAT) were found under these linkage peaks and may influence the levels of neural activity occurring in individuals participating in a spatial working-memory task.

French television talk: what tenses for past time?

On the basis of a transcribed French television corpus made of two news bulletins, two chat shows and one literary programme recorded in February 2003, this paper explores the claim that passé simple (PS) may still be used in prepared oral discourse (Pfister 1974). The corpus does not provide support for that use on television, but it seems to suggest a shift from temporal to aspectual features in French television talk: a perfective presentation prevails on a past presentation. This trend would need to be confirmed by a larger television corpus, tested in other types of oral discourse and tested on written corpora.

An assessment of the learning benefits of using a web-based learning environment when teaching accounting

The impact and use of information and communication technology on learning outcomes for accounting students is not well understood. This study investigates the impact of design features of Blackboard 1 used as aWeb-based Learning Environment (WBLE) in teaching undergraduate accounting students. Specifically, this investigation reports on a number of Blackboard design features (e.g. delivery of lecture notes, announcements, online assessment and model answers) used to deliver learning materials regarded as necessary to enhance learning outcomes. Responses from 369 on-campus students provided data to develop a regression model that seeks to explain enhanced participation and mental effort. The final regression shows that student satisfaction with the use of a WBLE is associated with five design features or variables. These include usefulness and availability of lecture notes, online assessment, model answers, and online chat.

Online interviewing in psychology: reflections on the process

The internet is used across a range of disciplines to conduct qualitative research and qualitative psychologists are increasingly turning to the internet as a medium for conducting interviews. In this article we explore the first author’s experience of conducting synchronous online interviews using instant messaging or ‘chat’ software. We highlight the costs and benefits of conducting online interviews and reflect on the development of a rapport with participants within this medium. In particular, we consider how researchers can attempt to make online interviewing less abrupt and more conversational, how researchers can demonstrate ‘listening’ and how insider/outsider status of the interviewer effects interaction within online interviews.

A unification-based natural language interface to a database.

An implementation of a Lexical Functional Grammar (LFG) natural language front-end to a database is presented, and its capabilities demonstrated by reference to a set of queries used in the Chat-80 system. The potential of LFG for such applications is explored. Other grammars previously used for this purpose are briefly reviewed and contrasted with LFG. The basic LFG formalism is fully described, both as to its syntax and semantics, and the deficiencies of the latter for database access application shown. Other current LFG implementations are reviewed and contrasted with the LFG implementation developed here specifically for database access. The implementation described here allows a natural language interface to a specific Prolog database to be produced from a set of grammar rule and lexical specifications in an LFG-like notation. In addition to this the interface system uses a simple database description to compile metadata about the database for later use in planning the execution of queries. Extensions to LFG's semantic component are shown to be necessary to produce a satisfactory functional analysis and semantic output for querying a database. A diverse set of natural language constructs are analysed using LFG and the derivation of Prolog queries from the F-structure output of LFG is illustrated. The functional description produced from LFG is proposed as sufficient for resolving many problems of quantification and attachment.
