The subject-matter of this essay is gender justice in language which, as I argue, may be achieved through the development of a gender-related approach to linguistic human rights. The last decades of the 20th century, globally marked by a “gender shift” in attitudes to language policy, gave impetus to the social movement for promoting linguistic gender equality. It was initiated in Western Europe and nowadays is moving eastwards, as ideas of gender democracy progress into developing countries. But, while in western societies gender discrimination through language, or linguistic sexism, was an issue of concern for over three decades, in developing countries efforts to promote gender justice in language are only in their infancy. My argument is that to promote gender justice in language internationally it is necessary to acknowledge the rights of women and men to equal representation of their gender in language and speech and, therefore, raise a question of linguistic rights of the sexes. My understanding is that the adoption of the Universal Declaration of Linguistic Rights in 1996 provided this opportunity to address the problem of gender justice in language as a human rights issue, specifically as a gender dimension of linguistic human rights.

Heavy metal pollution is a matter of concern in industrialised countries. Contrary to organic pollutants, heavy metals are not metabolically degraded. This fact has two main consequences: its bioremediation requires another strategy and heavy metals can be indefinitely recycled. Yeast cells of Saccharomyces cerevisiae are produced at high amounts as a by-product of brewing industry constituting a cheap raw material. In the present work, the possibility of valorising this type of biomass in the bioremediation of real industrial effluents containing heavy metals is reviewed. Given the autoaggregation capacity (flocculation) of brewing yeast cells, a fast and off-cost yeast separation is achieved after the treatment of metal-laden effluent, which reduces the costs associated with the process. This is a critical issue when we are looking for an effective, eco-friendly, and low-cost technology. The possibility of the bioremediation of industrial effluents linked with the selective recovery of metals, in a strategy of simultaneous minimisation of environmental hazard of industrial wastes with financial benefits from reselling or recycling the metals, is discussed.

Swarm Intelligence (SI) is a growing research field of Artificial Intelligence (AI). SI is the general term for several computational techniques which use ideas and get inspiration from the social behaviours of insects and of other animals. This paper presents hybridization and combination of different AI approaches, like Bio-Inspired Techniques (BIT), Multi-Agent systems (MAS) and Machine Learning Techniques (ML T). The resulting system is applied to the problem of jobs scheduling to machines on dynamic manufacturing environments.

Introdução: O impacto do transporte diário das mochilas tornou-se uma área de preocupação da saúde pública, sendo necessária uma urgente mudança de comportamentos das crianças, educadores e cuidadores. Objetivos: O objetivo do presente estudo foi avaliar a influência da leitura do livro “Os Meninos das Costas Perfeitas” na mudança de comportamentos de estudantes do 1º e 4º anos. Métodos: Efetuou-se um estudo quase – experimental, onde se avaliou o efeito da leitura do livro, efetuada por pais ou professores, na mudança de comportamentos de estudantes (E) do 1º e 4º ano, voluntários, de uma escola de Felgueiras composto por 36 E (grupo experimental - GE). O grupo de controlo (GC), não sujeito à leitura do livro, foi constituído por 40 E do 1º e 4º ano de uma escola de Famalicão. Elaboraram-se dois questionários, um para avaliar subjetivamente os comportamentos dos E e outro para avaliar a perceção dos cuidadores (C) acerca da mudança de comportamentos dos E. Mediu-se do peso dos E e das mochilas e, nos modelos de mochila com duas alças, a distância de C7 ao topo da mochila, para avaliar a sua posição nas costas. Todos os instrumentos foram aplicados antes da leitura e após 3 meses. Resultados: O GE melhorou significativamente a posição da mochila nas costas (χ²=6,702; p=0,035) e a organização do material no seu interior (χ²=32,864; p <0,001) (χ²=15,587; p <0,001) quando comparado com o GC. Os C percecionaram uma melhoria significativa no ajuste da mochila às costas (χ²=6,231; p=0,013) e uma melhor organização do material no interior da mochila quando comparado com os C dos GC (χ²=5,394; p=0,020; χ²=14,266; p <0,001; χ²=5,365, p=0,021; p=0,021). Conclusão: A leitura do livro demonstrou ser eficaz numa mudança de comportamentos dos estudantes relacionados com o uso da mochila, que se tornaram mais saudáveis.
