Comunicação Interna e Gestão de Pessoas: Interfaces e perspectivas de integração e diálogo nas organizações

Esta dissertação tem como objetivo destacar a importância da integração entre as áreas de comunicação e de gestão de pessoas para o planejamento e desenvolvimento da comunicação interna nas organizações, bem como levantar algumas oportunidades de parceria entre as áreas. Busca-se também compreender o papel da área de gestão de pessoas nos processos comunicacionais e discutir a importância do diálogo e da participação na melhoria da comunicação com os públicos internos. Os novos contextos sociais e a inserção das organizações neste ambiente serviram como cenário para essa investigação e realçaram a importância do Pensamento Complexo como embasamento teórico. Utilizou-se como metodologia norteadora o levantamento bibliográfico do assunto e a realização de entrevistas semiestruturadas com especialistas das áreas de Comunicação Organizacional e da Administração com ênfase em Gestão de Pessoas. Compreende-se que adotando o pensamento complexo e a visão transdisciplinar como alicerce dessa interação a comunicação interna integrada será capaz de promover o diálogo e a participação e, com isso, ir além da visão técnico-instrumental para vencer as barreiras da departamentalização e atuar estrategicamente com a gestão de pessoas.

A Comunicação Mediada por Interfaces Digitais: a interação humana com os jogos digitais em celulares.

O trabalho é um estudo exploratório sobre o processamento de mensagens de entretenimento. O objetivo do trabalho foi propor e testar um modelo de processamento de mensagens dedicado à compreensão de jogos digitais. Para realizar tal tarefa realizou-se um extenso levantamento de técnicas de observação de usuários diante de softwares e mídias, para conhecer as qualidades e limitações de cada uma dessas técnicas, bem como de sua abordagem do problema. Também foi realizado um levantamento dos modelos de processamento de mensagens nas mídias tradicionais e nas novas mídias. Com isso foi possível propor um novo modelo de análise de processamento de mensagens de entretenimento. Uma vez criado o modelo teórico, fez-se preciso testar se os elementos propostos como participantes desse processo estavam corretos e se seriam capazes de capturar adequadamente as semelhanças e diferenças entre a interação entre jogadores e as diferentes mídias. Por essa razão, estruturou-se uma ferramenta de coleta de dados, que foi validada junto a designers de jogos digitais, uma vez que esses profissionais conhecem o processo de criação de um jogo, seus elementos e objetivos. Posteriormente, foi feito um primeiro teste, junto a praticantes de jogos digitais de diversas idades em computadores pessoais e TV digital interativa, a fim e verificar como os elementos do modelo relacionavam-se entre si. O teste seguinte fez a coleta de dados de praticantes de jogos digitais em aparelhos celulares, tendo como objetivo capturar como se dá a formação de uma experiência através do processamento da mensagem de entretenimento num meio cujas limitações são inúmeras: tamanho de tela e teclas, para citar algumas delas. Como resultado, verificou-se, por meio de testes estatísticos, que jogos praticados em meios como computadores pessoais atraem mais por seus aspectos estéticos, enquanto a apreciação de um jogo em aparelhos celulares depende muito mais de sua habilidade de manter a interação que um jogo praticado em PC. Com isso conclui-se que o processamento das mensagens de entretenimento depende da capacidade dos seus criadores em entender os limites de cada meio e usar adequadamente os elementos que compõe o ambiente de um jogo, para conseguir levar à apreciação do mesmo.(AU)

AS INTERFACES DA PROMOÇÃO DA SAÚDE E UM PROGRAMA DE APRENDIZAGEM PROFISSIONAL

O trabalho desenvolvido com adolescentes, pensando na promoção de sua saúde, bem como em seu desenvolvimento saudável por meio de espaços que atendam suas necessidades, tem sido de responsabilidade também de organizações sociais. Em especial, quando se tem o objetivo de prepará- los para o mundo do trabalho, porém com uma proposta mais ampla, ou seja, como uma preparação para suas relações na vida, pela passagem de um processo de aprendizagem, de amadurecimento, por meio da construção de ações significativas para vida. Esta é a proposta do Centro de Orientação ao Adolescente de Campinas COMEC , organização não governamental, que conta com um Progr ama de Aprendizagem Profissional- PAP . Sendo assim, esse estudo tem como objetivo caracterizar, por meio de prontuários, uma amostra de 280 adolescentes, compreender a percepção deles no processo vivido e identificar as expectativas na admissão, demissão e desligamento do programa - PAP. A pesquisa teve como participantes adolescentes de 14 a 17 anos, do gênero feminino e masculino, do ensino fundamental e médio (7ª série E.F até 3ª série E.M). Os formulários foram preenchidos em três momentos: primeiro quando o adolescente participava da seleção para ingressar no programa, segundo, quando ele iniciava o trabalho na empresa e no término do contrato do adolescente com o programa. Os resultados obtidos por meio dos prontuários dos adolescentes mostraram que a percepção que eles têm a respeito do programa é positiva. Perceberam-se sentimentos de medo, insegurança, alegrias e desejos a respeito das atividades que os preparam para a inserção no mercado formal de trabalho, e o quanto o acompanhamento pelo programa permite outro olhar para esta inclusão. Ainda que o trabalho juvenil não seja a solução para as necessidades econômicas de muitas famílias, o trabalho educativo tem sido visto como uma forma de permitir que o adolescente vivencie sua primeira experiência de trabalho, respeitando sua condição de pessoa em desenvolvimento. Porém, em alguns casos, acabam por contribuir de forma significativa no orçamento familiar.(AU)

Combining the power of online crowdsourcing with creative writing user interfaces

The goal of this work was to provide professional and amateur writers with a new way of enhancing their productivity and mental well-being, by helping them overcoming writers block and being able to achieve a state of optimal experience while writing. Our approach is based on bringing together different components to create what we call a creative moment. A creative moment is composed by an image, a text, a mood, a location and a color. The color presented in the creative moment varied according to the mood that was associated to the creative moment. With the creative moments we hoped that our users could have a way to easily trigger their creativity and have a kick start in their work. The prototyping of a web crowdsourcing platform, named CreativeWall, and a Microsoft Word Add-In, that was used on the user study performed, is described and their implementations are discussed. The user study reveals that our approach does have a positive influence in the productivity of the participants when compared with another existing approach. The study also revealed that our approach can ease the process of achieving a state of optimal experience by enhancing one of the dimensions presented on the Flow Theory. At the end we present what we consider would be some possible future developments for the concept created during the development of this work.

Novel cationic polymers for use at biological interfaces

One of the main problems with the use of synthetic polymers as biomaterials is the invasion of micro-organisms causing infection. A study of the properties of polymeric antibacterial agents, in particular polyhexamethylene biguanide, has revealed that the essential components for the design of a novel polymeric antibacterial are a balance between hydrophilicity and hydrophobicity coupled with sites of cationicity. The effect of cation incorporation on the physical properties of hydrogels has been investigated. Hydrogel systems copolymerised with either N-vinyl imidazole or dimethylaminoethyl methacrylate have been characterised in terms of their water binding, mechanical and surface properties. It has been concluded that the incorporation of these monomers does not adversely affect the properties of such hydrogels and that these materials are potential candidates for further development for use in biomedical applications. It has been reported that hydro gels with ionic character may increase the deposition of biological material onto the hydrogel surface when it is in contact with body fluids. An investigation into the deposition characteristics of hydrogels containing the potentially cationic monomers has been carried out, using specific protein adsorption and in vitro spoilation techniques. The results suggest that at low levels of cationicity, the deposition of positively charged proteins is reduced without adversely affecting the uptake of the other proteins. The gross deposition characteristics were found to be comparable to some commercially available contact lens materials. A preliminary investigation into the development of novel antibacterial polymers has been completed and some novel methods of bacterial inhibition discussed. These methods include development of an hydrogel whose potential application is as a catheter coating.

Design and implementation of graphical user interfaces for complex simulations

The development of increasingly powerful computers, which has enabled the use of windowing software, has also opened the way for the computer study, via simulation, of very complex physical systems. In this study, the main issues related to the implementation of interactive simulations of complex systems are identified and discussed. Most existing simulators are closed in the sense that there is no access to the source code and, even if it were available, adaptation to interaction with other systems would require extensive code re-writing. This work aims to increase the flexibility of such software by developing a set of object-oriented simulation classes, which can be extended, by subclassing, at any level, i.e., at the problem domain, presentation or interaction levels. A strategy, which involves the use of an object-oriented framework, concurrent execution of several simulation modules, use of a networked windowing system and the re-use of existing software written in procedural languages, is proposed. A prototype tool which combines these techniques has been implemented and is presented. It allows the on-line definition of the configuration of the physical system and generates the appropriate graphical user interface. Simulation routines have been developed for the chemical recovery cycle of a paper pulp mill. The application, by creation of new classes, of the prototype to the interactive simulation of this physical system is described. Besides providing visual feedback, the resulting graphical user interface greatly simplifies the interaction with this set of simulation modules. This study shows that considerable benefits can be obtained by application of computer science concepts to the engineering domain, by helping domain experts to tailor interactive tools to suit their needs.

Chemical reactions at nuclear fuel-clad interfaces

This thesis presents a study of the chemical reactions that may occur at the fuel- clad interfaces of fuel elements used in advanced gas-coooled reactors (A.G.R.) The initial investigation involved a study of the inner surfaces of irradiated stainless steel clad and evidence was obtained to show that fission products, in particular tellerium, were associated with reaction products on these surfaces. An accelerated rate of oxidation was observed on the inner surfaces of a failed A.G.R. fuel pin. It is believed that fission product caesium was responsible for this enhancement. A fundamental study of the reaction between 20%Cr/25%Ni/niobium stabilised stainless steel and tellerium was then undertaken over the range 350 - 850 degrees C. Reaction occurred with increasing rapidity over this range and long term exposure at ≤ 750 degrees resulted in intergranular attack of the stainless steel and chromium depletion. The reaction on unoxidised steel surfaces involved the formation of an initial iron-nickel-tellerium layer which subsequently transformed to a chromium telluride product during continued exposure. The thermodynamic stabilities of the steel tellurides were determined to be chromium telluride > nickel telluride > iron telluride. Oxidation of the stainless steel surface prior to tellerium exposure inhibited the reaction. However reaction did occur in regions where the oxide layer had either cracked or spalled.

Semantic search components:a blueprint for effective query language interfaces

Formulating complex queries is hard, especially when users cannot understand all the data structures of multiple complex knowledge bases. We see a gap between simplistic but user friendly tools and formal query languages. Building on an example comparison search, we propose an approach in which reusable search components take an intermediary role between the user interface and formal query languages.

Fluctuations and correlations in sandpiles and interfaces with boundary pinning

Interfaces are studied in an inhomogeneous critical state where boundary pinning is compensated with a ramped force. Sandpiles driven off the self-organized critical point provide an example of this ensemble in the Edwards-Wilkinson (EW) model of kinetic roughening. A crossover from quenched to thermal noise violates spatial and temporal translational invariances. The bulk temporal correlation functions have the effective exponents β1D∼0.88±0.03 and β2D∼0.52±0.05, while at the boundaries βb,1D/2D∼0.47±0.05. The bulk β1D is shown to be reproduced in a randomly kicked thermal EW model.

Power electronic interfaces for low voltage residential networks

A proposal to increase the existing residential LV grid voltage from 230 V to 300 V has been made in order to increase existing network capacity. A power-electronic AC-AC converter is then used to provide 230 V at each property. The equipment can also provide power-quality improvements to the network and load. Several constraints such as temperature rise at the converter location lead to a converter design requiring very high efficiency. In this paper different AC/AC converter topologies are presented which compares the power quality benefits, size and efficiency of each converter. The design and the control technique of the most suitable topology are verified using simulation and preliminary experimentally results of prototype hardware are also included. © 2013 IEEE.

Involvement of tissue transglutaminase in the stabilisation of biomaterial/tissue interfaces important in medical devices

Tissue transglutaminase (tTG) has recently been established as a novel cell surface adhesion protein that binds with high affinity to fibronectin in the pericellular matrix. In this study, we have made use of this property to enhance the biocompatibility of poly(epsilon-caprolactone) (PCL), a biomaterial currently used in bone repair. Poly(epsilon-caprolactone) discs were first coated with fibronectin and then tTG. The surface localisation of the two proteins was confirmed using ELISA and the tTG shown to be active on the surface by incorporation of biotin cadaverine into the fibronectin coating. When human osteoblasts (HOBs) were seeded onto the coated polymer surfaces in serum free medium, the surface coated with fibronectin and then tTG showed an increase in the spreading of the cells as compared to the surface coated with fibronectin alone, when analysed using environmental scanning electron microscopy. The presence of tTG had no effect on HOB cell differentiation when analysed by determining alkaline phosphatase activity. The use of tTG as a novel adhesion protein in this way may therefore have considerable potential in forming a stable tissue/biomaterial interface for application in medical devices.

Web Interfaces Destined for People with Disabilities

One of the main characteristics of the world that we live in is the access to information and one of the main ways to reach the information is the Internet. Most Internet sites put accessibility problem on a secondary plan. If we try to define this concept (accessibility) we could say that accessibility it’s a way to offer access to information for the people with disabilities. For example blind people can’t navigate on the Internet like usual people. For that reason Internet sites have to put at their disposal ways to make their content known to this people. Accessibility does not refer only at blind people the web accessibility refers to all people who lost their ability to access the Internet sites. The web accessibility includes every disability that stops people with disabilities to access the web sites content like hearing disability, neurological and cognitive. People that have low speed Internet connection or with low performance computers can use the web accessibility.
