- Transgenerational inheritance of paternal neurobehavioral phenotypes: stress, addiction, ageing and metabolismPublication . Yuan, Ti-Fei; Li, Ang; Sun, Xin; Ouyang, Huan; Campos, Carlos; Rocha, Nuno; Arias-Carrión, Oscar; Machado, Sergio; Hou, Gonglin; So, Kwok FaiEpigenetic modulation is found to get involved in multiple neurobehavioral processes. It is believed that different types of environmental stimuli could alter the epigenome of the whole brain or related neural circuits, subsequently contributing to the long-lasting neural plasticity of certain behavioral phenotypes. While the maternal influence on the health of offsprings has been long recognized, recent findings highlight an alternative way for neurobehavioral phenotypes to be passed on to the next generation, i.e., through the male germ line. In this review, we focus specifically on the transgenerational modulation induced by environmental stress, drugs of abuse, and other physical or mental changes (e.g., ageing, metabolism, fear) in fathers, and recapitulate the underlying mechanisms potentially mediating the alterations in epigenome or gene expression of offsprings. Together, these findings suggest that the inheritance of phenotypic traits through male germ-line epigenome may represent the unique manner of adaptation during evolution. Hence, more attention should be paid to the paternal health, given its equivalently important role in affecting neurobehaviors of descendants.
- Social representation of “hearing loss”: Cross cultural exploratory study in India, Iran, Portugal, and the UKPublication . Manchaiah, Vinaya; Danermark, Berth; Ahmadi, Tayebeh; Tomé, David; Zhao, Fei; Li, Qiang; Krishna, Rajalakshmi; Germundsson, PerHearing loss is one of the most common chronic conditions in older adults. In audiology literature, several studies have examined the attitudes and behavior of people with hearing loss; however, not much is known about the manner in which society in general views and perceives hearing loss. This exploratory study was aimed at understanding the social representation of hearing loss (among the general public) in the countries of India, Iran, Portugal, and the UK. We also compared these social representations. The study involved a cross-sectional design, and participants were recruited using the snowball sampling method. A total of 404 people from four countries participated in the study. Data were collected using a free-association task where participants were asked to produce up to five words or phrases that came to mind while thinking about hearing loss. In addition, they were also asked to indicate if each word they presented had positive, neutral, or negative associations in their view. Data were analyzed using various qualitative and quantitative methods. The most frequently occurring categories were: assessment and management; causes of hearing loss; communication difficulties; disability; hearing ability or disability; hearing instruments; negative mental state; the attitudes of others; and sound and acoustics of the environment. Some categories were reported with similar frequency in most countries (eg, causes of hearing loss, communication difficulties, and negative mental state), whereas others differed among countries. Participants in India reported significantly more positive and fewer negative associations when compared to participants from Iran, Portugal, and the UK. However, there was no statistical difference among neutral responses reported among these countries. Also, more differences were noted among these countries than similarities. These findings provide useful insights into the public perception of hearing loss that may prove useful in public education and counseling.
- Competências a potenciar: novas formas de agir na construção do conhecimentoPublication . Braga, InêsNo âmbito duma investigação que cruza a área científica da Ciência da Informação com a Educação, elegendo como objeto de estudo a Literacia da Informação (LI), selecionaramse um conjunto de competências de LI, reconhecidas como mais importantes e mencionadas em vasta literatura sobre o tema, com destaque para alguns Referenciais internacionais. Pretende-se averiguar qual o papel da formação ministrada em diferentes licenciaturas de uma escola de ensino superior politécnico e refletir sobre que competências são mais desenvolvidas nos estudantes de diferentes cursos, comparando aqueles que iniciam e os que terminam a sua formação. Para além dos estudantes, destaca-se, neste estudo, a intervenção dos professores das referidas licenciaturas, ambos os grupos inquiridos através de questionários online. Também os elementos responsáveis pela coordenação dos oito cursos de primeiro ciclo em análise e a bibliotecária da instituição são envolvidos, neste caso, através de entrevistas semidirigidas, contribuindo para uma investigação que se pretende o mais completa possível e com a robustez decorrente do cruzamento de vários dados. Recorrendo a uma abordagem metodológica quantitativa e qualitativa, num interessante jogo de perceções consonantes ou divergentes entre estes atores cruciais do processo educativo, os resultados e a sua interpretação permitem refletir sobre a necessidade de adotar novas posturas e atuações no complexo processo de formação e de desenvolvimento de competências de LI. Estas devem ser adequadas aos perfis desejáveis dos diplomados do ensino superior, profissionais e cidadãos que se pretende que obtenham sucesso nas diferentes áreas da sua vida, revelando-se, em suma, indivíduos infoincluídos, ativos e participativos face às mudanças, desafios e crises do século XXI.
