Multilevel and multidimensional scale for online trust

This paper examines the nature of the construct of consumers' trust toward the electronic channel of their financial institution. Through a study of a total of 372 individual users of Internet banking in Spain, we have managed to develop a third-order measuring instrument that integrates a total of seven dimensions. The exploratory and confirmatory factor analyses were used to test the validation and reliability of the proposed scale. Findings provide useful information to professionals who seek to identify how customer's trust is formed in the online channel and in the financial sector.

Demand for and availability of online support to stop smoking

OBJECTIVES: Estimate the frequency of online searches on the topic of smoking and analyze the quality of online resources available to smokers interested in giving up smoking. METHODS: Search engines were used to revise searches and online resources related to stopping smoking in Brazil in 2010. The number of searches was determined using analytical tools available on Google Ads; the number and type of sites were determined by replicating the search patterns of internet users. The sites were classified according to content (advertising, library of articles and other). The quality of the sites was analyzed using the Smoking Treatment Scale- Content (STS-C) and the Smoking Treatment Scale - Rating (STS-R). RESULTS: A total of 642,446 searches was carried out. Around a third of the 113 sites encountered were of the 'library' type, i.e. they only contained articles, followed by sites containing clinical advertising (18.6) and professional education (10.6). Thirteen of the sites offered advice on quitting directed at smokers. The majority of the sites did not contain evidence-based information, were not interactive and did not have the possibility of communicating with users after the first contact. Other limitations we came across were a lack of financial disclosure as well as no guarantee of privacy concerning information obtained and no distinction made between editorial content and advertisements. CONCLUSIONS: There is a disparity between the high demand for online support in giving up smoking and the scarcity of quality online resources for smokers. It is necessary to develop interactive, customized online resources based on evidence and random clinical testing in order to improve the support available to Brazilian smokers.

Health problems awareness during travel among faculty members of a large university in Latin America: preliminary report

Health safety during trips is based on previous counseling, vaccination and prevention of infections, previous diseases or specific problems related to the destination. Our aim was to assess two aspects, incidence of health problems related to travel and the traveler's awareness of health safety. To this end we phone-interviewed faculty members of a large public University, randomly selected from humanities, engineering and health schools. Out of 520 attempts, we were able to contact 67 (12.9%) and 46 (68.6%) agreed to participate in the study. There was a large male proportion (37/44, 84.1%), mature adults mostly in their forties and fifties (32/44, 72.7%), all of them with higher education, as you would expect of faculty members. Most described themselves as being sedentary or as taking occasional exercise, with only 15.9% (7/44) taking regular exercise. Preexisting diseases were reported by 15 travelers. Most trips lasted usually one week or less. Duration of the travel was related to the destination, with (12h) or longer trips being taken by 68.2% (30/44) of travelers, and the others taking shorter (3h) domestic trips. Most travelling was made by air (41/44) and only 31.8% (14/44) of the trips were motivated by leisure. Field research trips were not reported. Specific health counseling previous to travel was reported only by two (4.5%). Twenty seven of them (61.4%) reported updated immunization, but 11/30 reported unchecked immunizations. 30% (9/30) reported travel without any health insurance coverage. As a whole group, 6 (13.6%) travelers reported at least one health problem attributed to the trip. All of them were males travelling abroad. Five presented respiratory infections, such as influenza and common cold, one neurological, one orthopedic, one social and one hypertension. There were no gender differences regarding age groups, destination, type of transport, previous health counseling, leisure travel motivation or pre-existing diseases. Interestingly, the two cases of previous health counseling were made by domestic travelers. Our data clearly shows that despite a significant number of travel related health problems, these highly educated faculty members, had a low awareness of those risks, and a significant number of travels are made without prior counseling or health insurance. A counseling program conducted by a tourism and health professional must be implemented for faculty members in order to increase the awareness of travel related health problems.

Pre-travel health advice for human immunodeficiency virus-infected travelers, from Rio de Janeiro

Counseling for human immunodeficiency virus infected travelers is becoming increasingly specialized. Previous studies have reported the experience of HIV-infected travelers from temperate-climate countries but little is known about HIV-infected travelers from tropical countries. A retrospective study was conducted on HIV-infected travelers presenting at a travel health clinic in Rio de Janeiro. Eleven journeys by ten people were recorded. Brazil (Amazon region and Northeast) was the destination for six journeys. Other destinations were Peru, Angola, Europe and Asia. Nine attendees were undergoing antiretroviral therapy. Few HIV-infected people from Rio de Janeiro consulted a travel medicine specialist before traveling. Since they travel to destinations in Brazil and abroad where there are endemic diseases not encountered in Rio de Janeiro, careful pre-travel planning needs to be undertaken. Strategies for increasing the frequency of pre-travel consultations need to be developed, such as closer collaboration between HIV clinics and travel health clinics.

Redes sociais de saúde como grupos de suporte online na vida de pacientes com doenças cardiovasculares

Existe um aumento no conjunto de pacientes que utilizam a internet em busca de informações que possam melhorar suas condições de saúde. Nele, distinguem-se pacientes que procuram ambientes virtuais para expor experiências, dúvidas, opiniões, emoções e inclusive criar relacionamentos visando dar ou receber apoio. Nesse sentido, há uma crescente necessidade de estudar como estes ambientes podem repercutir na saúde dos pacientes. Este artigo tem por objetivo identificar na literatura científica estudos sobre a proliferação e impacto das comunidades virtuais conhecidas como Redes Sociais de Saúde ou Grupos de Suporte Online, voltados para doenças cardiovasculares, que podem ser úteis aos pacientes com determinadas doenças, permitindo-lhes obter informação e apoio emocional. Para o levantamento bibliográfico, foi realizada revisão sistemática da literatura com artigos publicados entre 2007-2012, nas bases de dados PubMed, Association for Computing Machinery e Institute of Electrical and Electronic Engineer, que se encontram relacionados com o tema proposto, e foram selecionados quatro artigos, segundo os critérios de inclusão dos métodos. Os resultados encontrados revelam dados interessantes, relevantes segundo o aspecto de saúde, os quais podem trazer alguns benefícios terapêuticos, destacando: provisão de suporte emocional, maior adesão ao tratamento, compartilhamento de informação sobre as doenças e obtenção de experiências de vida.

An MLSA-based online scheme for the rapid identification of Stenotrophomonas isolates

An online scheme to assign Stenotrophomonas isolates to genomic groups was developed using the multilocus sequence analysis (MLSA), which is based on the DNA sequencing of selected fragments of the housekeeping genes ATP synthase alpha subunit (atpA), the recombination repair protein (recA), the RNA polymerase alpha subunit (rpoA) and the excision repair beta subunit (uvrB). This MLSA-based scheme was validated using eight of the 10 Stenotrophomonas species that have been previously described. The environmental and nosocomial Stenotrophomonas strains were characterised using MLSA, 16S rRNA sequencing and DNA-DNA hybridisation (DDH) analyses. Strains of the same species were found to have greater than 95% concatenated sequence similarity and specific strains formed cohesive readily recognisable phylogenetic groups. Therefore, MLSA appeared to be an effective alternative methodology to amplified fragment length polymorphism fingerprint and DDH techniques. Strains of Stenotrophomonas can be readily assigned through the open database resource that was developed in the current study (www.steno.lncc.br/).

Programa de mentoria online para professores iniciantes: fases de um processo

Neste artigo analisamos as fases evidenciadas no desenvolvimento do Programa de Mentoria do Portal dos Professores da Universidade Federal de São Carlos (SP). O programa se caracteriza por ser online e é dirigido para professores dos anos iniciais do ensino fundamental com até cinco anos de experiência. Foi conduzido por três pesquisadoras e onze mentoras (professoras experientes) que acompanharam individualmente, a distância e por meio de correspondências eletrônicas, 56 professoras iniciantes durante períodos entre seis meses a dois anos e meio. Do ponto de vista teórico consideramos a literatura relativa à aprendizagem e desenvolvimento profissional da docência; início da carreira docente; processos de mentoria e educação a distância. Metodologicamente desenvolvemos uma pesquisa-ação a partir de estratégias construtivo-colaborativas. As principais fontes de dados foram as correspondências trocadas entre mentoras e professoras iniciantes; diários reflexivos de mentoras e professoras iniciantes; redação de casos de ensino pelas professoras iniciantes; registros de observação das reuniões semanais ocorridos entre pesquisadoras e mentoras. Os resultados apontam que os processos de mentoria investigados ocorrem segundo fases distintas (fase inicial ou de aproximação; fase de desenvolvimento ou aprofundamento; fase de desligamento) com características, objetivos e procedimentos próprios.

Uso da RMN como um sensor online em processos industriais

Nuclear magnetic resonance (NMR) is one of the most versatile analytical techniques for chemical, biochemical and medical applications. Despite this great success, NMR is seldom used as a tool in industrial applications. The first application of NMR in flowing samples was published in 1951. However, only in the last ten years Flow NMR has gained momentum and new and potential applications have been proposed. In this review we present the historical evolution of flow or online NMR spectroscopy and imaging, and current developments for use in the automation of industrial processes.
