Human Rights in the Management Literature: Leading Publications and Research Agenda

This is the final version of the article. Available from Universidade Federal do Rio de Janeiro via the DOI in this record.This paper identifies and examines leading publications on human rights within the management literature. For that, we used features of a bibliometric analysis – specifically exploring product and impact indicators – in order to identify the leading publications on human rights that were examined aiming to portray how the issue has been addressed within this field. Moreover, by identifying the key articles and concepts adopted by the leading publications, this paper offers an interpretation of the academic context that enabled the emergence of a human rights approach within the management field. Thus, a contribution of this paper is to highlight how the debate on human rights in management has been strengthened, identifying articles and journals that can be a source of reference for future research. Our study has identified a shift in the discussion regarding human rights. During the last decade the topic, which was initially focused on the role of states in guaranteeing human rights, has started to examine the relationship between organizations and society. Such transformation has placed human rights as both, a responsibility and a duty of corporations. It is suggested that the literature on ethics and corporate social responsibility (CSR) was the entrance for a human rights approach within management literature. However, the discipline has already engaged in elaborating different interpretation of human rights. Our research shows the potential of human rights in consolidate a research agenda on corporate impact in our societies

New Functionalized Macroparticles for Environmentally Sustainable Biofilm Control in Water Systems

Reverse osmosis (RO) depends on biocidal agents to control the operating costs associated to biofouling, although this implies the discharge of undesired chemicals into the aquatic environment. Therefore, a system providing pre-treated water free of biocides arises as an interesting solution to minimize the discharge of chemicals while enhancing RO filtration performance by inactivating bacteria that could form biofilms on the membrane system. This work proposes a pretreatment approach based on the immobilization of an industrially used antimicrobial agent (benzalkonium chloride-BAC) into millimetric aluminum oxide particles with prior surface activation with DA-dopamine. The antimicrobial efficacy of the functionalized particles was assessed against Escherichia coli planktonic cells through culturability and cell membrane integrity analysis. The results showed total inactivation of bacterial cells within five min for the highest particle concentration and 100% of cell membrane damage after 15 min for all concentrations. When reusing the same particles, a higher contact time was needed to reach the total inactivation, possibly due to partial blocking of immobilized biocide by dead bacteria adhering to the particles and to the residual leaching of biocide. The overall results support the use of Al2O3-DA-BAC particles as antimicrobial agents for sustainable biocidal applications in continuous water treatment systems
