Infância protegida? A Imagem mediática das crianças aos olhos do provedor

A exposição mediática de crianças, sobretudo de crianças em risco, é com frequência um tema delicado do ponto de vista da ética jornalística. Prestando-se a um tratamento informativo que por vezes arrisca tocar o sentimento do público, a infância tem-se revelado um campo particularmente fértil de matéria noticiosa. Se as questões relacionadas com a educação e a saúde infantil estão largamente nas páginas dos jornais e nos ecrãs, em consonância com a crescente atenção dos media aos temas sociais em geral, os casos de justiça, muitas vezes implicando casos de abuso sobre menores, são cada vez mais matéria inescapável para jornalistas. Tomando por referência um estudo da cobertura que a imprensa e a televisão fizeram de crianças em risco em 2008, os autores procuram, neste texto, conhecer a intervenção específica dos Provedores dos Leitores, Ouvintes e Telespectadores em matéria de protecção da imagem da infância nos media. O objectivo é problematizar o papel da literacia mediática para a promoção de acções de sensibilização do público e dos profissionais dos media relativamente aos direitos da criança. Nos termos de uma ética participada pelos cidadãos, procurar-se-á argumentar o papel dos provedores como mecanismo de educação para um consumo crítico dos media.

Cognitive stimulation for portuguese older adults with cognitive impairment: a randomized controlled trial of efficacy, comparative duration, feasibility and experiential relevance

Although some studies point to cognitive stimulation as a beneficial therapy for older adults with cognitive impairments, this area of research and practice is still lacking dissemination and is underrepresented in many countries. Moreover, the comparative effects of different intervention durations remain to be established and, besides cognitive effects, pragmatic parameters, such as cost-effectiveness and experiential relevance to participants, are seldom explored. In this work, we present a randomized con- trolled wait-list trial evaluating 2 different intervention durations (standard 1⁄4 17 vs brief 1⁄4 11 sessions) of a cognitive stimulation program developed for older adults with cognitive impairments with or without dementia. 20 participants were randomly assigned to the standard duration intervention program (17 sessions, 1.5 months) or to a wait-list group. At postintervention of the standard intervention group, the wait-list group crossed over to receive the brief intervention program (11 sessions, 1 month). Changes in neuropsychological, functionality, quality of life, and caregiver outcomes were evaluated. Experience during intervention and costs and feasibility were also evaluated. The current cognitive stimulation programs (ie, standard and brief) showed high values of experiential relevance for both intervention durations. High adherence, completion rates, and reasonable costs were found for both formats. Further studies are needed to definitively establish the potential efficacy, optimal duration, cost-effectiveness, and experiential relevance for participants of cognitive intervention approaches.

Data supporting the role of enzymes and polysaccharides during cassava postharvest physiological deterioration

This data article is referred to the research article entitled The role of ascorbate peroxidase, guaiacol peroxidase, and polysaccharides in cassava (Manihot esculenta Crantz) roots under postharvest physiological deterioration by Uarrota et al. (2015). Food Chemistry 197, Part A, 737746. The stress duo to PPD of cassava roots leads to the formation of ROS which are extremely harmful and accelerates cassava spoiling. To prevent or alleviate injuries from ROS, plants have evolved antioxidant systems that include non-enzymatic and enzymatic defence systems such as ascorbate peroxidase, guaiacol peroxidase and polysaccharides. In this data article can be found a dataset called newdata, in RData format, with 60 observations and 06 variables. The first 02 variables (Samples and Cultivars) and the last 04, spectrophotometric data of ascorbate peroxidase, guaiacol peroxidase, tocopherol, total proteins and arcsined data of cassava PPD scoring. For further interpretation and analysis in R software, a report is also provided. Means of all variables and standard deviations are also provided in the Supplementary tables (data.long3.RData, data.long4.RData and meansEnzymes.RData), raw data of PPD scoring without transformation (PPDmeans.RData) and days of storage (days.RData) are also provided for data analysis reproducibility in R software.
