Abstract
Purpose
The purpose of this paper is to address the use of sludge from water treatment plant (WTP sludge), in its natural form (wet), in the construction industry, especially in the production of concrete, evaluating the effects of replacing natural sand with different WTP sludge levels in the concrete properties.
Design/methodology/approach
The dosage study evaluated mixtures with replacement levels of 0, 5, 7 and 10 percent of wet sludge in relation to the mass of natural sand, analyzing their effects on mechanical properties and water absorption in concrete with water/cement (w/c) ratios of 0.45, 0.55 and 0.65.
Findings
From the results obtained, it is possible to note that the addition of WTP sludge in its natural form (wet) reduces the strength of concrete. However, from a technical point of view, a level of replacement of up to 5 percent for applications in concrete is suitable, provided that it is not structural concrete.
Practical implications
Further studies should be conducted to verify the influence of the replacement of sand for heat-treated sludge in concrete properties, also analyzing the environmental viability linked to the calcination process.
Originality/value
Few studies are conclusive in relation to the use of WTP sludge in concrete production. This study shows statistically the negative effect of the addition of wet sludge in the mechanical properties and in the water absorption of concretes from different w/c ratios.

Abstract
Purpose
The distress that is associated with auditory hallucinations, or voices, is well documented. However, increasingly research into this phenomenon is also capturing those who cope with their voices, and live meaningful lives. Peer support is a popular and useful way in which to learn to manage the distress for voice-hearers. The Hearing Voices Network (HVN) acts as an umbrella organisation for which research, training and peer support groups exist (www.intervoiceonline.org). Despite the growing amount of peer support groups established, there is to date no published material on these groups. The purpose of this paper is to discuss these issue.
Design/methodology/approach
The present study used Interpretive Phenomenological Analysis to explore the experiences of four informants across three New South Wales HVN groups.
Findings
Results suggest that the social connections, value of sharing and desire for more group members are all important within the group. Beyond the group, informants described the increased willingness to talk to others about their voice experiences, improvements in sense of self and a positive change in their relationship with their voices.
Originality/value
The study demonstrates the importance of peer participation in the mental health workforce and the provision of safe spaces for those with lived experience to share and learn from each other in meaningful ways. Research implications include the need for further research measuring outcomes on a larger scale for these support groups.

Abstract
Latin America offers a unique opportunity to reimagine educational leadership through its complex and intersectional frameworks where rematriation movements and liberatory pedagogies are the driving forces for “postponing the end of the world,” as proposed by Ailton Krenak (2020). While currently Latin American democracies are less than ideal as environmental and Indigenous initiatives have been directly attacked by ultraconservative politics, there are consistent foundations that deepen in each context by leading the way to a hopeful future. These foundations are the loud voices in the Latin American continent and they are multilingually expressed in Quechua, Guarani, Aymara, and more, as is also immersed in critical literacies; in processes of conscientização; experienced in the arts and the theater of the Oppressed; and loudly coming from the slums and the lungs of women like Mercedes Sosa, and many more. These are the absolute breakthroughs of hope we will continue to listen, follow, work with, and feel. Such breakthroughs are the pedagogies and the educational leadership of hope across Latin America, a region which has pushed to center on Indigenous mobilization and guidance.

Abstract
After a technocratic period predominating in mobility literature and practice, the rhetoric of participation has been incorporated as a vital condition for the sustainable mobility agenda and, more recently, for achieving transport and mobility justice. Considering the social significance of mobility beyond simple movement and participation as a term that can accommodate a wide range of motivations and implications, this chapter explores the complex interplay of participation and mobility in the global south context. To this end, this study adopts the spaces for participation framework to investigate the multiple roles of participation in urban mobility. With a focus on the Brazilian context, this chapter uncovers the nature, dynamics, and reach of invited and claimed spaces for participation in mobility planning. Using Rio de Janeiro as the case study site, the chapter examines the invited spaces for participation enabled by the city's mobility plan and analyses whether marginalised populations engage with and/or create further spaces for participation. This was achieved through document analysis, online photo-elicitation interviews with residents of Favela Santa Marta as well as semi-structured interviews with municipal government professionals and representatives of non-government organisations involved in the development of Rio's mobility plan. The chapter discusses the interconnectedness or lack of, within invited and claimed spaces for participation and the multiplicity of meanings attributed to participation and mobility by different actors. The chapter closes with a reflection on what this means for participatory mobility planning in Brazil but which may apply to similar regions in the global south.

Abstract
Purpose
It was aimed to propose and test a theoretical model to evaluate how some dimensions of environmental awareness influence the intention of consuming organic products using gender as a control variable.
Design/methodology/approach
The research was developed through quantitative methodology with the use of multivariate data analysis (PLS-SEM). The model uses a second-order construct. Although, it was conducted in a nonprobabilistic way using a convenience sample, with 213 university students.
Findings
It was confirmed the relation between the environmental awareness dimensions' influence and the intention to buy organic products that is also influenced according to the consumers' gender. There is a more positive effect and intensity in the organics' purchase by women.
Research limitations/implications
The nonprobabilistic nature in addition to the use of the convenience sample, factors that do not allow the generalization of the results, are some limitations. Moreover, the dimensions of environmental awareness proposed do not include all of the motivators about the organic consumption.
Practical implications
The results identified the factors that motivate the intention to consume organic products in Brazilian context and can contribute to managerial strategies formulation in order to increase the value perceived by the customer in relation to the consumption of these products.
Originality/value
This paper presents a deeper understanding about the dynamics between the factors that can guide the choice for organic products, besides providing a greater theoretical and empirical support tested by the use of a second-order construct.

Abstract
Purpose
Considering the different roles universities can perform to contribute to sustainable development, it is through teaching and outreach that they might be able to connect to the academic and local communities the most. The purpose of this study is to investigate the extent to which energy sustainability is being considered in campus teaching and outreach activities of different higher education institutions worldwide. In this context, this exploratory study was developed.
Design/methodology/approach
Through an online survey, a group of 36 universities from all continents was inquired about the level of sustainability in energy aspects of teaching and outreach activities, including curriculum change, training courses for staff and the regularity of outreach projects.
Findings
The results allowed global analysis concerning challenges and opportunities of these educational activities. This study also touches upon the interconnection between these practices and the contribution of universities towards the 2030 Agenda, and how universities can expand their activities and contribute practically to society. In terms of practical contributions, this study provides recommendations for higher education institutions to develop further in the area of energy sustainability through teaching and outreach.
Originality/value
Energy is a sustainability aspect relatively well covered by actions on campus operations, but there is a paucity of studies connecting this topic to teaching and outreach activities. This study is an approach to not only fill this gap but also reinforce the university role and contribution to the Sustainable Development Goals.

Abstract
Purpose
The purpose of this paper is to report on the development and validation of a consumer power scale comprising a personal and a social power dimension. Personal power refers to consumers’ perceived ability to resist and ignore a firm’s marketing efforts. Social power refers to consumers’ perceived ability to influence a firm’s actions.
Design/methodology/approach
Following established scale development procedures, the construct definition and item generation preceded five studies that establish the scale’s dimensionality, psychometric properties and external, predictive and nomological validity.
Findings
Consumer power was modeled as a reflective first-order, formative second-order latent construct. The consumer power scale is psychometrically sound and possesses external and discriminant validity with regard to other power-related measures. Consumer power mediates the relation between consumers’ cognitive control and consumer satisfaction and between perceived choice and emotional responses.
Research limitations/implications
This research uses episodic recall tasks to elicit power perceptions in various contexts. Results suggest that the scale is useful in comparative and longitudinal tracking of consumers’ perceptions of power in relation to a firm.
Originality/value
Building on a comprehensive literature review and rigorous scale development, this paper introduces a scale of consumer power that comprises a personal and a social power dimension. A critical analysis of and a predictive validity test of the scale against existing power scales highlight its unique contribution. The scale lends itself to further theory tests regarding antecedents, consequences and moderators of consumer power.
