A rápida expansão da Internet vem trazendo conseqüências substanciais para a sociedade, na forma como as pessoas se relacionam, estudam, trabalham, adquirem e consomem produtos e serviços. Para as empresas é inquestionável a importância da adequação deste novo meio aos seus compostos de marketing, principalmente no sentido de estabelecer um canal de comunicação que possa conectá-las ainda mais aos seus clientes. Porém, para que esta aproximação ocorra, é necessário que sejam conhecidos os desejos e valores que norteiam e influenciam o processo de compra do consumidor online. Esta dissertação busca, justamente, uma aproximação entre estas duas questões: por um lado, as iniciativas de marketing das empresas, por meio de seus Web sites; por outro, os valores que influenciam o comportamento dos consumidores virtuais. O objetivo consiste em comparar as ações de marketing realizadas pelas empresas, por meio de seus Web sites, com o valor para o cliente manifestado pelos consumidores. Para atingir tal objetivo, optou-se por um estudo com múltiplas fontes de coletas de dados e triangulação de dados na análise. Primeiramente, foram realizadas entrevistas pessoais, individuais e em profundidade com 05 (cinco) consumidores de Internet, visando identificar os valores subjetivos relacionados ao consumo no ambiente online. Nesta fase da pesquisa foi utilizado o Modelo de Valor para o Cliente de Woodruff e Gardial (1996). Em seguida, foram analisados Web sites de empresas, a fim de detectar a coerência existente entre os pontos considerados de valor pelos consumidores e as estratégias e ações efetivamente implementadas pelas empresas. Optou-se pela utilização do modelo de Ho (1997), cujo trabalho propõe um método de avaliação de Web sites a partir da perspectiva de valor criado para o consumidor. Os resultados demonstraram que, apesar do crescimento da Internet, alguns desses valores ainda estão latentes, com pouca ou nenhuma iniciativa das empresas no sentido de supri-los.

This dissertation of Mestrado investigated the performance and quality of web sites. The target of the research is the proposal of an integrated model of evaluation of services of digital information in web educational sites. The universe of the research was constituted by eighteen Brazilian Universities that offer after-graduation courses, in the levels of mestrado and doutorado in the area of Engineering of Production. The adopted methodology was a descriptive and exploratory research, using the technique of systematic comment and focus group, for the collection of the data, using itself changeable independent dependents and, through the application of two instruments of research. The analysis protocol was the instrument adopted for evaluation and attainment of qualitative results. E the analysis grating was applied for evaluation and attainment of the quantitative results. The qualitative results had identified to the lack of standardization of web sites, under the attributes of content, hierarchy of information, design of the colors and letters. It of accessibility for carriers of auditory and visual special necessities was observed inexistence, as well as the lack of convergence of medias and assistivas technologies. The language of the sites also was evaluated and all present Portuguese only language. The general result demonstrated in grafico and tables with classification of the Universities, predominating the Good note As for the quantitative results, analysis method ed was estatistico, in order to get the descriptive and inferencial result between the dependent and independent variaveis. How much a category of analysis of the services of the evaluated sites, was found it props up and the index generality weighed. These results had served of base for ranking of existence or inexistence the Universities, how much of the information of services in its web sites. In analysis inferencial the result of the test of correlation or association of the independent variaveis (level, concept of the CAPES and period of existence of the program) with the caracteristicas, called was gotten categories of services. For this analysis the estatisticos methods had been used: coefficient of Spearman and the Test of Fisher. But the category you discipline of the Program of Mestrado presented significance with variavel independent and concept of the CAPES. Main conclusion of this study it was ausencia of satandardization o how much to the subjective aspects, design, hierarchy of information navigability and content precision and the accessibility inexistence and convergence. How much to the quantitative aspects, the information services offered by web sites of the evaluated Universities, still they do not present a satisfactory and including quality. Absence of strategies, adoption of tools web, techniques of institucional marketing and services that become them more interactive, navigable is perceived and with aggregate value

Recruiting and retaining new residents is critically important to communities that are experiencing either job growth or a declining population. City councils and village boards across the state often ask the question, “How can we bring in and keep new people today?” This issue has not gone unnoticed by the Nebraska Department of Economic Development or the University of Nebraska.

BACKGROUND: Many users search the Internet for answers to health questions. Complementary and alternative medicine (CAM) is a particularly common search topic. Because many CAM therapies do not require a clinician's prescription, false or misleading CAM information may be more dangerous than information about traditional therapies. Many quality criteria have been suggested to filter out potentially harmful online health information. However, assessing the accuracy of CAM information is uniquely challenging since CAM is generally not supported by conventional literature. OBJECTIVE: The purpose of this study is to determine whether domain-independent technical quality criteria can identify potentially harmful online CAM content. METHODS: We analyzed 150 Web sites retrieved from a search for the three most popular herbs: ginseng, ginkgo and St. John's wort and their purported uses on the ten most commonly used search engines. The presence of technical quality criteria as well as potentially harmful statements (commissions) and vital information that should have been mentioned (omissions) was recorded. RESULTS: Thirty-eight sites (25%) contained statements that could lead to direct physical harm if acted upon. One hundred forty five sites (97%) had omitted information. We found no relationship between technical quality criteria and potentially harmful information. CONCLUSIONS: Current technical quality criteria do not identify potentially harmful CAM information online. Consumers should be warned to use other means of validation or to trust only known sites. Quality criteria that consider the uniqueness of CAM must be developed and validated.

Technological and cultural factors influence access to health information on the web in multifarious ways. We evaluated structural differences and availability of communication services on the web in three diverse language and cultural groups: Chinese, English, and Spanish. A total of 382 web sites were analyzed: 144 were English language sites (38%), 129 were Chinese language sites (34%), and 108 were Spanish language sites (28%). We did not find technical differences in the number of outgoing links per domain or the total availability of communication services between the three groups. There were differences in the distribution of available services between Chinese and English sites. In the Chinese sites, there were more communication services between consumers and health experts. Our results suggest that the health-related web presence of these three cultural groups is technologically comparable, but reflects differences that may be attributable to cultural factors.

Web surveys are becoming increasingly popular in survey research. Compared with face-to-face, telephone and mail surveys, web surveys may contain a different and new source of measurement error and bias: the type of device that respondents use to answer the survey questions. To the best of our knowledge, this is the first study that tests whether the use of mobile devices affects survey characteristics and stated preferences in a web-based choice experiment. The web survey was carried out in Germany with 3,400 respondents, of which 12 per cent used a mobile device (i.e. tablet or smartphone), and comprised a stated choice experiment on externalities of renewable energy production using wind, solar and biomass. Our main finding is that survey characteristics such as interview length and acquiescence tendency are affected by the device used. In contrast to what might be expected, we find that, compared with respondents using desktop computers and laptops, mobile device users spent more time to answer the survey and are less likely to be prone to acquiescence bias. In the choice experiment, mobile device users tended to be more consistent in their stated choices, and there are differences in willingness to pay between both subsamples.

Bacterial lipoproteins have many important functions and represent a class of possible vaccine candidates. The prediction of lipoproteins from sequence is thus an important task for computational vaccinology. Naïve-Bayesian networks were trained to identify SpaseII cleavage sites and their preceding signal sequences using a set of 199 distinct lipoprotein sequences. A comprehensive range of sequence models was used to identify the best model for lipoprotein signal sequences. The best performing sequence model was found to be 10-residues in length, including the conserved cysteine lipid attachment site and the nine residues prior to it. The sensitivity of prediction for LipPred was 0.979, while the specificity was 0.742. Here, we describe LipPred, a web server for lipoprotein prediction; available at the URL: http://www.jenner.ac.uk/LipPred/. LipPred is the most accurate method available for the detection of SpaseIIcleaved lipoprotein signal sequences and the prediction of their cleavage sites.

Currently the media have made many new tools on their websites in order to broaden the dialogue with its users, a feature that has been called interactivity. The objective of this research is to describe the interactive resources of Chilean media websites. The analysis was conducted at 20 sites using a pattern of six dimensions with interactive forms which are today using identified. The findings indicate that digital media Chileans are expanding the possibilities of dialogue with users on social media, especially Twitter and Facebook, and the mediauser interaction is monological, that is to say, from the media to the user, but with very low feedback.
