Uso da Internet na elaboração do trabalho de conclusão de curso pelos alunos de Enfermagem

A enfermagem se destaca como consumidora de tecnologia em diversos contextos: ensino, pesquisa e assistência. Como os alunos do curso de Enfermagem utilizam a internet para o processo de produção de Trabalhos de Conclusão de Curso (TCC)? Com o intuito de responder a essa questão e compreender melhor como a internet vem sendo utilizada na construção dos TCC dos alunos de Enfermagem, este trabalho tem os seguintes objetivos: avaliar a utilização da internet na elaboração de TCC; investigar o uso da internet por esses; identificar as bases de dados utilizadas; levantar as principais dificuldades e/ou facilidades; e descrever como a internet é usada para buscar a literatura produzida. Trata-se de um estudo descritivo, seccional, com abordagem quantitativa, desenvolvido em duas instituições de ensino superior em Teresina – Piauí, sendo uma de caráter privado e outra de caráter público. A pesquisa teve como amostragem os alunos de Enfermagem do 8º período das duas instituições. É relevante considerar que o acesso democrático e a falta de conhecimento frente à internet ainda são realidade em nossa sociedade, o que nos remete à necessidade de implementar estratégias de educação relacionadas à utilização da internet como ferramenta para a construção do conhecimento em saúde e enfermagem.

Abordagem do internet marketing aliada ao comportamento do consumidor em Moçambique

A presente dissertação procura compreender o grau de aceitação dos consumidores na comunidade moçambicana em relação à recente abordagem da internet nos meios de comunicação. Desta forma, o objetivo principal deste trabalho consistiu em avaliar o impacto do internet marketing no comportamento dos consumidores, assumindo como ponto de partida e suporte, estudos já realizados e aplicados em Portugal. Divagando sobre a problemática foi traçada a seguinte questão de partida para a investigação em curso: De que forma o aparecimento do internet marketing veio afetar o comportamento do consumidor atual em Moçambique? O uso da internet está a crescer rapidamente em todo mundo, assumindo deste modo um papel primordial no quotidiano dos consumidores e como consequência tem impulsionado a alteração dos seus padrões de consumo. O mesmo comportamento dos consumidores tem vindo a modificar a forma como o indivíduo vê a compra de bens e serviços, podendo dizer-se que o consumidor atual passou claramente a assumir as suas próprias escolhas, segundo as suas reais necessidades. Assente nesta tendência do meio digital, surge-nos um novo tipo de consumidor, mais autónomo, inteligente, exigente e informado, o consumidor 2.0. Como conclusão deste estudo, aplicado à realidade moçambicana, iremos constatar que apesar da crescente utilização deste novo método de comunicação o país e a população em geral ainda não estão preparados para esta nova abordagem do marketing.

Estudo do impacto do tamanho máximo da carga da trama Ethernet no perfil do Tráfego IPV6 na Internet

A transição entre a versão 4 para a versão 6 do Internet Protocol (IP) vem ocorrendo na comunidade da Internet. No entanto, a estrutura interna dos protocolos IPv4 e IPv6, em detalhe no tamanho dos seus cabeçalhos, pode provocar alterações no perfil tráfego da rede. Este trabalho estuda as mudanças nas características de tráfego de rede, avaliando o que mudaria se o tráfego gerado fosse apenas IPv6 em vez de IPv4. Este artigo estende-se uma pesquisa anterior, abordando novas questões, mas usando os registos de dados reais disponíveis publicamente. É adotada uma metodologia de engenharia reversa nos pacotes IPv4 capturados, permitindo assim inferir qual a carga original no computador tributário e em seguida reencapsular essa carga em novos pacotes usando restrições de encapsulamento IPv6. Conclui-se que, na transição de IPv4 para IPv6, haverá um aumento no número de pacotes transmitidos na Internet.

The use of computer-based learning tools for teaching and clinical purposes: Interactive computing strategy for Iraq

Medical universities and teaching hospitals in Iraq are facing a lack of professional staff due to the ongoing violence that forces them to flee the country. The professionals are now distributed outside the country which reduces the chances for the staff and students to be physically in one place to continue the teaching and limits the efficiency of the consultations in hospitals. A survey was done among students and professional staff in Iraq to find the problems in the learning and clinical systems and how Information and Communication Technology could improve it. The survey has shown that 86% of the participants use the Internet as a learning resource and 25% for clinical purposes while less than 11% of them uses it for collaboration between different institutions. A web-based collaborative tool is proposed to improve the teaching and clinical system. The tool helps the users to collaborate remotely to increase the quality of the learning system as well as it can be used for remote medical consultation in hospitals.

A fuzzy approach for the network congestion problem

In the recent years, the unpredictable growth of the Internet has moreover pointed out the congestion problem, one of the problems that historicallyha ve affected the network. This paper deals with the design and the evaluation of a congestion control algorithm which adopts a FuzzyCon troller. The analogyb etween Proportional Integral (PI) regulators and Fuzzycon trollers is discussed and a method to determine the scaling factors of the Fuzzycon troller is presented. It is shown that the Fuzzycon troller outperforms the PI under traffic conditions which are different from those related to the operating point considered in the design.

A parallel genetic algorithm for the Steiner Problem in Networks

This paper presents a parallel genetic algorithm to the Steiner Problem in Networks. Several previous papers have proposed the adoption of GAs and others metaheuristics to solve the SPN demonstrating the validity of their approaches. This work differs from them for two main reasons: the dimension and the characteristics of the networks adopted in the experiments and the aim from which it has been originated. The reason that aimed this work was namely to build a comparison term for validating deterministic and computationally inexpensive algorithms which can be used in practical engineering applications, such as the multicast transmission in the Internet. On the other hand, the large dimensions of our sample networks require the adoption of a parallel implementation of the Steiner GA, which is able to deal with such large problem instances.

The application of implant technology for cybernetic systems

Objective: To assess the usefulness, compatibility, and long-term operability of a microelectrode array into the median nerve of the left arm of a healthy volunteer, including perception of feedback stimulation and operation of an instrumented prosthetic hand. Setting: The study was carried out from March 14 through June 18, 2002, in England and the United States. Results: The blindfolded subject received feedback information, obtained from force and slip sensors on the prosthetic hand, and subsequently used the implanted device to control the hand by applying an appropriate force to g rip an unseen object. Operability was also demonstrated remotely via the Internet, with the subject in New York, NY, and the prosthetic hand in Reading, England. Finally, the subject was able to control an electric wheelchair, via decoded signals from the implant device, to select the direction of travel by opening and closing his hand. The implantation did not result in infection or any perceivable loss of hand sensation or motion control. The implant was finally extracted because of mechanical fatigue of the percutaneous connection. Further testing after extraction has not indicated any measurable long-term defects in the subject. Conclusions: This implant may allow recipients to have abilities they would otherwise not possess. The response to stimulation improved considerably during the trial, suggesting that the subject learned to process the incoming information more effectively.

Position paper on the future of social networking

Social networking mediated by web sites is a relatively new phenomenon and as with all technological innovations there continues to be a period of both technical and social adjustment to fit the services in with people’s behaviours, and for people to adjust their practices in the light of the affordances provided by the technology. Social networking benefits strongly from large scale availability. Users gain greater benefit from social networking services when more of their friends are using them.This applies in social terms, but also in eLearning and professional networks. The network effect provides one explanation for the popularity of internet based social networking sites (SNS) because the number of connections between people which can be maintained by using them is greatly increased in comparison to the networks available before the internet. The ability of users to determine how much they trust information available to them from contacts within their social network is important in almost all modes of use. As sources of information on a range of topics from academic to shopping advice, the level of trust which a user can put in other nodes is a key aspect of the utility of the system.

Computer-mediated communication in distance MA programmes: the student's perspective

This paper reports on a study of computer-mediated communication within the context of a distance MA in TEFL programme which used an e-mail discussion list and then a discussion board. The study focused on the computer/Internet access and skills of the target population and their CMC needs and wants. Data were collected from 63 questionnaires and 6 in-depth interviews with students. Findings indicate that computer use and access to the Internet are widespread within the target population. In addition, most respondents indicated some competence in Internet use. No single factor emerged as an overriding inhibiting factor for lack of personal use. There was limited use of the CMC tools provided on the course for student–student interaction, mainly attributable to time constraints. However, most respondents said that they would like more CMC interaction with tutors. The main factor which would contribute to greater Internet use was training. The paper concludes with recommendations and suggestions for learner training in this area.

Conceptualising and measuring the equity of online brands

Although brand equity is an important source of competitive advantage online, previous conceptualisations and measures overlook the unique characteristics of the internet that render consumers co-creators of brand value. In view of this, a threephased research programme was undertaken to identify the facets of online retail/service (ORS) brand equity and then develop and validate a scale for its measurement. ORS brand equity was found to be a second order construct with five correlated yet distinct dimensions: emotional connection, online experience, responsive service nature, trust, and fulfilment. A series of tests showed that the ensuing 12-item scale has strong psychometric properties. The implications of this research for marketing researchers and practitioners are discussed.

Taking the brand promise online: challenges and opportunities

Starting from the fact that a 'brand' is a universal concept regardless of environment, but its enactment changes according to environment, this paper provides pointers about brand building on the internet. It presents a three-level model of a brand to help organisations characterise their brands' promises. By expanding this model it then considers how a brand's promise can be enacted on the internet in order to assess the coherence of the brand. Through considering how some organisations have taken advantage of the internet, it highlights three factors critical for success. Ten key action points for marketers are presented.

Taking the shopping centre online: new models in e-commerce

Purpose – This paper aims to provide a brief re´sume´ of previous research which has analysed the impact of e-commerce on retail real estate in the UK, and to examine the important marketing role of the internet for shopping centre managers, and retail landlords. Design/methodology/approach – Based on the results from a wider study carried out in 2003, the paper uses case studies from two different shopping centres in the UK, and documents the innovative uses of both web-based marketing and online retailing by organisations that historically have not directly been involved in the retailing process. Findings – The paper highlights the importance of considering online sales within a multi-channel approach to retailing. The two types of emerging shopping centre model which are identified are characterised by their ultimate relationship with the physical shopping centre on whose web site they reside. These can be summarised as: the “centre-led” approach, and the “brand-led” or “marketing-led” approach. Research limitations/implications – The research is based on a limited number of in-depth case studies and secondary data. Further research is needed to monitor the continuing impact of e-commerce on retail property and the marketing strategies of shopping centre managers and owners. Practical implications – Internet-based sales provide an important adjunct to conventional retail sales and an important source of potential risk for landlords and tenants in the real estate investment market. Regardless of whether retailers use the internet as a sales channel, as a product-sourcing tool, or merely to provide information to the consumer, the internet has become a keystone within the greater retail marketing mix. The findings have ramifications for understanding the way in which landlords are structuring their retail property to defray potential risks. Originality/value – The paper examines shopping centre online marketing models for the first time in detail, and will be of value to retail occupiers, owners and other stakeholders of shopping centres.

Ecommerce and retail in the UK and USA

Presents findings from separate research projects conducted in the UK and the USA on the impact of e-commerce on retailers and retail property. Examines differences between UK and US retailers along several dimensions: Internet strategies, perceptions of the Internet, barriers to e-commerce growth, and future space requirements. Overall, findings indicate that UK and US retailers have similar attitudes about e-commerce. Specifically, retailers in both samples perceive little threat or impact from e-commerce. Second, barriers to e-commerce growth are similar for UK and US retailers and include fulfillment and security issues. Third, UK and US retailers indicate that their retail space needs will remain the same or increase in the short term, despite the threat of e-commerce. Finally, both sets of retailers believe that entertainment is an important strategy if shopping centers are to remain viable.

Analysing the factors that influence tag choice based on semiotic analysis and activity theory

Social tagging has become very popular around the Internet as well as in research. The main idea behind tagging is to allow users to provide metadata to the web content from their perspective to facilitate categorization and retrieval. There are many factors that influence users' tag choice. Many studies have been conducted to reveal these factors by analysing tagging data. This paper uses two theories to identify these factors, namely the semiotics theory and activity theory. The former treats tags as signs and the latter treats tagging as an activity. The paper uses both theories to analyse tagging behaviour by explaining all aspects of a tagging system, including tags, tagging system components and the tagging activity. The theoretical analysis produced a framework that was used to identify a number of factors. These factors can be considered as categories that can be consulted to redirect user tagging choice in order to support particular tagging behaviour, such as cross-lingual tagging.
