Attention to health cues on product packages

The objectives of the study were (a) to examine which information and design elements on dairy product packages operate as cues in consumer evaluations of product healthfulness, and (b) to measure the degree to which consumers voluntarily attend to these elements during product choice. Visual attention was measured by means of eye-tracking. Task (free viewing, product healthfulness evaluation, and purchase likelihood evaluation) and product (five different yoghurt products) were varied in a mixed within-between subjects design. The free viewing condition served as a baseline against which increases or decreases in attention during product healthfulness evaluation and purchase likelihood evaluation were assessed. The analysis revealed that the only element operating as a health cue during product healthfulness evaluation was the nutrition label. The information cues used during purchase likelihood evaluation were the name of the product category and the nutrition label. Taken together, the results suggest that the only information element that consumers consistently utilize as a health cue is the nutrition label and that only a limited amount of attention is devoted to read nutrition labels during purchase likelihood evaluations. The study also revealed that the probability that a consumer will read the nutrition label during the purchase decision process is associated with gender, body mass index and health motivation.

As declarações do arguido e a estrutura acusatória do processo penal português

Changes to the rules concerning the admissibility of statements read in trial, previously provided by the defendant, despite its apparent simplicity, undermine the criminal procedural architecture projected from the constitutional structure accusatory criminal procedure. The principle that in judging only can be valued the evidence produced before the judge gives rise the production of evidence by the prosecution in the investigation phase.

Comunicar com símbolos em contexto inclusivo : aplicação de software educativo

O presente estudo de investigação-ação partiu da necessidade de investigar e aprofundar a aprendizagem do mecanismo da leitura e da escrita numa criança com Paralisia Cerebral mediante a aplicação do software educativo “Comunicar com Símbolos”. O trabalho desenvolveu-se inicialmente num Centro Escolar de um Agrupamento de Escolas da zona centro do país, no distrito de Santarém, passando a realizar-se, após avaliação diagnóstica, numa Instituição Particular de Segurança Social - Centro de Deficientes Profundos da mesma região e analisa essencialmente o desenvolvimento da aprendizagem da leitura e da escrita numa criança com Paralisia Cerebral Espástica Bilateral com predomínio nos membros inferiores através da aplicação de dez sessões planificadas com base na utilização do software educativo Comunicar com Símbolos, da Cnotinfor – Imagina. Após a intervenção e a análise dos resultados, concluiu-se que o programa informático supramencionado apresenta vantagens significativas na consolidação da leitura e da escrita da criança com Paralisia Cerbral. Este trabalho de natureza interventiva não pretende, de forma alguma, dar respostas únicas na implementação de estratégias na melhoria do desenvolvimento do mecanismo da leitura e da escrita em crianças com Paralisia Cerebral, mas apenas contribuir para uma reflexão aprofundada sobre a importância da aplicação das tecnologias de apoio na prática pedagógica com crianças com Necessidades Educativas Especiais, no geral.

Ler um sintoma = Lire un symptôme

Este texto chama a atenção para o facto da psicanálise não ser só uma questão de saber escutar, mas também de saber ler, em particular de ler o real dos restos sintomáticos para além do sentido, privando o sintoma do sentido.

Predicting the ability to lip-read in children who have a hearing loss

This study aims to discover if a variety of factors related to a child's education and audiologic history predict a child's ability to lip-read.

On the generation mechanisms of short-scale unbalanced modes in rotating two-layer flows with vertical shear

We report on the results of a laboratory investigation using a rotating two-layer annulus experiment, which exhibits both large-scale vortical modes and short-scale divergent modes. A sophisticated visualization method allows us to observe the flow at very high spatial and temporal resolution. The balanced long-wavelength modes appear only when the Froude number is supercritical (i.e. $F\,{>}\,F_\mathrm{critical}\,{\equiv}\, \upi^2/2$), and are therefore consistent with generation by a baroclinic instability. The unbalanced short-wavelength modes appear locally in every single baroclinically unstable flow, providing perhaps the first direct experimental evidence that all evolving vortical flows will tend to emit freely propagating inertia–gravity waves. The short-wavelength modes also appear in certain baroclinically stable flows. We infer the generation mechanisms of the short-scale waves, both for the baro-clinically unstable case in which they co-exist with a large-scale wave, and for the baroclinically stable case in which they exist alone. The two possible mechanisms considered are spontaneous adjustment of the large-scale flow, and Kelvin–Helmholtz shear instability. Short modes in the baroclinically stable regime are generated only when the Richardson number is subcritical (i.e. $\hbox{\it Ri}\,{<}\,\hbox{\it Ri}_\mathrm{critical}\,{\equiv}\, 1$), and are therefore consistent with generation by a Kelvin–Helmholtz instability. We calculate five indicators of short-wave generation in the baroclinically unstable regime, using data from a quasi-geostrophic numerical model of the annulus. There is excellent agreement between the spatial locations of short-wave emission observed in the laboratory, and regions in which the model Lighthill/Ford inertia–gravity wave source term is large. We infer that the short waves in the baroclinically unstable fluid are freely propagating inertia–gravity waves generated by spontaneous adjustment of the large-scale flow.

A calibrated, non-invasive method for measuring the internal interface height field at high resolution in the rotating, two-layer annulus

We describe a remote sensing method for measuring the internal interface height field in a rotating, two-layer annulus laboratory experiment. The method is non-invasive, avoiding the possibility of an interaction between the flow and the measurement device. The height fields retrieved are accurate and highly resolved in both space and time. The technique is based on a flow visualization method developed by previous workers, and relies upon the optical rotation properties of the working liquids. The previous methods returned only qualitative interface maps, however. In the present study, a technique is developed for deriving quantitative maps by calibrating height against the colour fields registered by a camera which views the flow from above. We use a layer-wise torque balance analysis to determine the equilibrium interface height field analytically, in order to derive the calibration curves. With the current system, viewing an annulus of outer radius 125 mm and depth 250 mm from a distance of 2 m, the inferred height fields have horizontal, vertical and temporal resolutions of up to 0.2 mm, 1 mm and 0.04 s, respectively.

A capture–recapture approach for screening using two diagnostic tests with availability of disease status for the test positives only

The article considers screening human populations with two screening tests. If any of the two tests is positive, then full evaluation of the disease status is undertaken; however, if both diagnostic tests are negative, then disease status remains unknown. This procedure leads to a data constellation in which, for each disease status, the 2 × 2 table associated with the two diagnostic tests used in screening has exactly one empty, unknown cell. To estimate the unobserved cell counts, previous approaches assume independence of the two diagnostic tests and use specific models, including the special mixture model of Walter or unconstrained capture–recapture estimates. Often, as is also demonstrated in this article by means of a simple test, the independence of the two screening tests is not supported by the data. Two new estimators are suggested that allow associations of the screening test, although the form of association must be assumed to be homogeneous over disease status. These estimators are modifications of the simple capture–recapture estimator and easy to construct. The estimators are investigated for several screening studies with fully evaluated disease status in which the superior behavior of the new estimators compared to the previous conventional ones can be shown. Finally, the performance of the new estimators is compared with maximum likelihood estimators, which are more difficult to obtain in these models. The results indicate the loss of efficiency as minor.
