Print versus website physical activity programs: A randomized trial

Mediated physical activity interventions can reach large numbers of people at low cost. Programs delivered through the mail that target the stage of motivational readiness have been shown to increase activity. Communication technology (websites and e-mail) might provide a means for delivering similar programs. Randomized trial conducted between August and October 2001. Participants included staff at an Australian university (n=655; mean AGE=43, standard deviation, 10 years). Participants were randomized to either an 8-week, stage-targeted print program (Print) or 8-week, stage-targeted website (Web) program. The main outcome was change in self-reported physical activity.

Portuguese india, the Politics of Print and a Questionable Modernity

Este artigo-recensão do livro da Dra. Rochelle Pinto, Between Empires: Print and Politics in Goa, Oxford University Press, New Delhi, 2007, pp. 209 analisa este excelente estudo das implicações modernistas da imprensa na Índia Portuguesa. A autora distingue a modernidade da peninsula imbérica da modernidade inglesa. Salienta a diferença entre as duas modernidades. O que parece ser de pouco valor neste estudos é a tendência orientalista que os jovens investigadores são forçados a assumir: passa pela adoração pelos autores euro-americanos, subalternizando ou quase ignorando os estudos mais competentes dos investigadores orientais. Este complexo da inferioridade poderá levar ainda muito tempo para ser ultrapassada.

Students’ reading behavior: digital vs. print preferences in portuguese context

The aim of this paper is to present the main Portuguese results from a multi-national study on reading format preferences and behaviors from undergraduate students from Polytechnic Institute of Porto (Portugal). For this purpose we apply an adaptation of the Academic Reading Questionnaire previously created by Mizrachi (2014). This survey instrument has 14 Likert-style statements regarding the format influence in the students reading behavior, including aspects such as ability to remember, feelings about access convenience, active engagement with the text by highlighting and annotating, and ability to review and concentrate on the text. The importance of the language and dimension of the text to determine the preference format is also inquired. Students are also asked about the electronic device they use to read digital documents. Finally, some demographic and academic data were gathered. The analysis of the results will be contextualized on a review of the literature concerning youngsters reading format preferences. The format (digital or print) in which a text is displayed and read can impact comprehension, which is an important information literacy skill. This is a quite relevant issue for class readings in academic context because it impacts learning. On the other hand, students preferences on reading formats will influence the use of library services. However, literature is not unanimous on this subject. Woody, Daniel and Baker (2010) concluded that the experience of reading is not the same in electronic or print context and that students prefer print books than e-books. This thesis is reinforced by Ji, Michaels and Waterman (2014) which report that among 101 undergraduates the large majority self-reported to read and learn more when they use printed format despite the fact that they prefer electronically supplied readings instead of those supplied in printed form. On the other side, Rockinson-Szapkiw, et al (2013) conducted a study were they demonstrate that e-textbook is as effective for learning as the traditional textbook and that students who choose e-textbook had significantly higher perceived learning than students who chose to use print textbooks.

Activity of Tri-N-Butyl Tin maleate in carpets against Staphylococcus aureus and Aspergillus niger, verified through two methodologies: Inhibition Halo (HZ) and Inhibition Surface (Print)

The aim of the present study was to verify the activity of the Tri-N-Butyl Tin maleate compound against Staphylococcus aureus and Aspergillus niger, after its industrial application in 40 samples of carpets of different materials (polypropylene, polyester, polyamide and wool). The qualitative assays were performed through two methodologies: Inhibition Halo (HZ) and Inhibition of Surface (Print). The carpet with the product inhibited 100% of bacterial (Staphylococcus aureus) and fungi (Aspergillus niger) growth, under the conditions of this study. The microbial inhibition was higher in upper portion of carpets. The methodologies employed appear to be adequate to test the bactericide and fungicide activities of the Tri-N-Butyl Tin maleate. The print methodology confirmed the results obtained by the inhibition zone assay. Further studies using the same methodologies are needed to confirm our results.

Do print para o tablet. Estudo de caso da Revista Proteste

Actualmente o contacto com uma notícia é feito em rede e através de diversos media, o Papel, a Internet, a Televisão, os Telemóveis e os Tablets. Como dispositivo técnico de leitura de notícias os Tablets são uma plataforma que apresenta os conteúdos da notícia de uma revista de forma diferente. A informação é apresentada através de soluções visuais e com uma nova narrativa, diferente das revistas tradicionais. Os conteúdos estão mais fragmentados, o leitor pode ver um vídeo, ouvir uma música, seleccionar uma informação através de um sistema de “árvore de decisão” carregando num simples botão, aceder a um hyperlink ou simplesmente visualizar um slideshow. Todos estes recursos interativos estão disponíveis. Os números de venda de Tablets induzem a que muitas editoras se adaptem a esta inovação e que desenvolvam os seus produtos editoriais neste novo suporte. A revista Proteste, o principal produto da linha generalista que abrange todos os domínios do equipamento e os serviços destinados ao consumidor, da Editora DecoProteste Editores para a defesa do consumidor, LDA, necessita de migrar para estes dispositivos para cativar novos públicos. A presença desta revista nos Tablets está actualmente disponível através de um pdf com interação diminuta. Esta limitação será o ponto de partida deste trabalho de Projeto. A proposta terá um novo layout, que será estruturado com base na revista tradicional em papel, o objetivo é privilegiar a fácil usabilidade e apreensão dos conteúdos pelo leitor. A aplicação será concebida através de software compatível com o utilizado na produção da revista. Serão seleccionados conteúdos já publicados e identificadas as respectivas fontes. O projecto centrar-se-á no design de uma aplicação na qual serão criados todos os elementos interactivos de forma a introduzir uma nova narrativa/storytelling na publicação onde o consumidor possa interagir. A identificação com a revista em papel será muito forte através de uma nomenclatura que nos remeterá para os conteúdos disponibilizados em papel, nomeadamente as rubricas, os testes comparativos com designação de uma Escolha Acertada, que define a melhor relação “qualidade/preço”, bem como a selecção dos produtos e serviços com melhor desempenho. Os estudos de preços, outro dos sectores fundamentais da informação disponível em papel, também serão abordados. O modo como consumimos informação mudou. Com boas “histórias” em mãos e através dos meios tecnológicos disponíveis é a altura ideal para poder contá-las.

From print to screen: changes and challenges facing the Brazilian publishing industry

The publishing industry is at a turning point. Facing the first major disruptive innovation in five centuries, its long-established structure and business model are at stake. Building on literature based on the pitfalls for incumbents, we interviewed key executives from the major publishers in Brazil to understand their perspective. We find that not only are they facing those pitfalls, but we also propose a new one, The Industry View Trap, concerning challenges created by convergence, the difficulty to deal with changes in the ecosystem and the fact that the very definition of the industry you're part of might have changed.

Identification of Wax Esters in Latent Print Residues by Gas Chromatography-Mass Spectromertry and Their Potential Use as Aging Parameters

Recent studies show that the composition of fingerprint residue varies significantly from the same donor as well as between donors. This variability is a major drawback in latent print dating issues. This study aimed, therefore, at the definition of a parameter that is less variable from print to print, using a ratio of peak area of a target compound degrading over time divided by the summed area of peaks of more stable compounds also found in latent print residues.Gas chromatography-mass spectrometry (GC/MS) analysis of the initial lipid composition of latent prints identifies four main classes of compounds that can be used in the definition of an aging parameter: fatty acids, sterols, sterol precursors, and wax esters (WEs). Although the entities composing the first three groups are quite well known, those composing WEs are poorly reported. Therefore, the first step of the present work was to identify WE compounds present in latent print residues deposited by different donors. Of 29 WEs recorded in the chromatograms, seven were observed in the majority of samples.The identified WE compounds were subsequently used in the definition of ratios in combination with squalene and cholesterol to reduce the variability of the initial composition between latent print residues from different persons and more particularly from the same person. Finally, the influence of a latent print enhancement process on the initial composition was studied by analyzing traces after treatment with magnetic powder, 1,2-indanedione, and cyanoacrylate.

Offset-print mottling measurement using machine vision

Mottling is one of the key defects in offset-printing. Mottling can be defined as unwanted unevenness of print. In this work, diameter of a mottle spot is defined between 0.5-10.0 mm. There are several types of mottling, but the reason behind the problem is still not fully understood. Several commercial machine vision products for the evaluation of print unevenness have been presented. Two of these methods used in these products have been implemented in this thesis. The one is the cluster method and the other is the band-pass method. The properties of human vision system have been taken into account in the implementation of these two methods. An index produced by the cluster method is a weighted sum of the number of found spots, and an index produced by band-pass method is a weighted sum of coefficients of variations of gray-levels for each spatial band. Both methods produce larger indices for visually poor samples, so they can discern good samples from the poor ones. The difference between the indices for good and poor samples is slightly larger produced by the cluster method. 11 However, without the samples evaluated by human experts, the goodness of these results is still questionable. This comparison will be left to the next phase of the project.
