English In their efforts to promote the Global Standards for the Education and Training of the Social Work Profession, the authors discovered the withering of the moral and political bases of social work practice in the West. The revitalization of the roots of social work is important to the promotion of social justice. French Dans leurs efforts pour promouvoir les Standards Mondiaux pour l’Enseignement et la Formation aux Professions Sociales, les auteurs découvrent le déclin des bases morales et politiques de la pratique du travail social en occident. La revitalisation des racines du travail social est importante pour la promotion de la justice sociale.

English Social work knowledge cannot be adequately articulated by the positivistic epistemology. It arises from the judgements rather than the techniques. Forms of knowledge acquisition and utilization must be reinvented so that there is a close and equal partnership among the profession, practitioners and students. This will enable social workers to discover, articulate and use their knowledge most effectively. French L'épistémologie positiviste ne permet d'articuler adéquatement le savoir en travail social. Celle-ci découle davantage des préjugés que des techniques. Les façons d'acquérir et d'utiliser le savoir demandent à être repensées de manière à établir un partenariat serré, sur une base d'égalité entre la profession, les practiciens et les étudiants. Les travailleurs sociaux pourront ainsi découvrir, articuler et exploiter le savoir de façon plus efficace. Spanish El conocimiento de trabajo social no puede ser adecuadamente articulado por la epistemología positivista. Ya que este conocimiento surge de opiniones, criterios más que técnicas. Formas de adquisición y utilización de conocimiento debe ser reinventada de tal manera que exista una colaboración igualitaria entre la profesión, practicantes y estudiantes. Esta colaboración ayudara trabajadores sociales a descubrir, articular y usar nuestro conocimiento más efectivamente.

Aluminium is biologically reactive and its ability to potentiate the immune response has driven its inclusion in both veterinary and human vaccines. Consequently, the need for unequivocal visualisation of aluminium in vivo has created a focused research effort to establish fluorescent molecular probes for this purpose. The most commonly used direct fluorescent labels for the detection of aluminium are morin (2′,3,4′,5,7-pentahydroxyflavone) and lumogallion [4-chloro-3-(2,4-dihydroxyphenylazo)-2-hydroxybenzene-1-sulphonic acid]. While the former has gained popularity in the detection of aluminium in plants and predominantly within root tips, the latter boasts greater sensitivity and selectivity for the detection of aluminium in human cells and tissues. Herein, we have developed a simplified morin staining protocol using the autofluorescence quenching agent, Sudan Black B. This modified protocol improves tissue morphology and increases analytical sensitivity, which allows intracellular aluminium to be detected in monocytes and when co-localised with senile plaques in human brain tissue of donors diagnosed with familial Alzheimer’s disease. Overall, our results demonstrate a simple approach to minimise false positives in the use of morin to unequivocally detect aluminium in vivo.Electronic supplementary materialThe online version of this article (10.1007/s00418-019-01809-0) contains supplementary material, which is available to authorized users.

This paper focuses on the new form of social participation created by information and communication technologies (ICTs), as experienced by an online professional community, SWForum, in Hong Kong. The group has expressed resistance and contributed to social welfare policy development since 1997, when frontline social workers were disempowered and lost their previously influential status. From this experience, we argue that the online community has created an arena for alternative discourse on social policy and it shows that the technology can be harnessed to create a more equitable participation in policy making in a society.
